Catfish do not see their food
Hello, generally, the fish do not need to see their food that well - they can smell it easily and find food even when it is dark. Newly added fish are often still shy and need some time to become accustomed. They should be given a weeks or perhaps even a bit longer for becoming acclimatized. You should offer them different treats during this time, preferably close to the animals. ...

Bottom gravel is clogged by sludge
this case advisable to simply use a gravel washer during the water changes. Generally, the problem occurs mainly with coarse gravel. The gaps are simply larger, allowing fish waste and uneaten food to sink in, while they stay on top in case of fine gravel and sand, where they can be washed into the filter more easily. Snails living on/in the gravel (especially Trumpet snails) are useful in...
How are fertilizer tablets optimally applied?

Snails eat plants

Goldfish got stuck, caudal fin is torn

It depends on the species you keep whether you rather feed them meaty food (sera O-Nip) or herbal food (sera Spirulina Tabs). sera marin Gourmet Nori (Nori algae) are an excellent additional food for algae eating shrimps that the...
Is it normal that Altolamprologus calvus grow very slowly?
Hello, Concerning "growth": yes, this is normal! Altolamprologus indeed grow very slowly. A 10 cm (3.9 in.) female would be a really capital specimen, although they may occasionally
Worms and Hydra
fish larvae (flatworms). The above mentioned nematodes (according to the way they appear they are definitely not parasitic species) and oligochaetes are entirely harmless. Concerning "live food": this is one possible source - however, you can also get them into the aquarium as eggs or larvae along with plants. Some of these invertebrate animals are so resistant that even severed body
"Moss balls" / Food amount
plants also withdraw only few nutrients from the water! The general rule: as many plants as possible, without obstructing the swimming space for the fish too much! Concerning "food amount": The food amount sounds reasonable, provided the tank is not stocked too densely. It is best to not feed at all 1 - 2 days per week. Best regards sera GmbH Dr. Bodo Schnell
How much water change in a 60 cm (23.6 in.) aquarium / How much food for catfish?
Hello, feeding catfish this way (sera Catfish Chips are, for instance, well suited) is alright, if (!) there is enough periphyton (algae etc.) and wood for rasping off. However, the tank is
No water changes while being away for three weeks? / Preparing food for vacation substitute
sustitute": prepare food portions in advance and write a date on them (plastic film cans from a photo shop are well suited) - lock away all other food! At least people who have no experience with aquariums tend to feed way too much, and this is much more dangerous than feeding somewhat sparingly. This, however, does not apply for juvenile fish and a few species that really need food daily...
Snails multiply too quickly
Hello, possible reasons also include live food or a latent presence that has caused rapid mass multiplication due to some factor, such as accidental overfeeding or a dead fish not discovered (snail food!). Such mass multiplication of small snails is mostly due to small ramshorn snail species. The good news up front: most snail species are entirely harmless in an aquarium if you keep an...
Tiger barb overeats
portions distributed over the day, and to distribute these portions to several different feeding places in the tank.

This will avoid intestinal fissures. Best regards sera GmbH ...
Piranhas in an aquarium

If necessary, dead food fish can be wiggled back and forth with a pair of food pliers ( not with the hand!) for triggering the hunting reflex. This especially applies for Piranhas that...
Treatment of swim bladder infections
Hello, sera baktopur direct (tablets to be dissolved in water) and sera baktoTabs (food tablets with the same anti-bacterial agent nifurpirinol - this of course requires that the fish still accept food!) will help against bacterial swimbladder infections. However, swimbladder infections often cause secondary deformation that is irrepareble in spite of treating the bacterial infection su
Continuously rising nitrate and phosphate levels / Snail invasion
the fresh water is low in nitrates and phosphates. Concerning "snail invasion": there is quite probably indeed a connection - too much food! Accordingly, you can reduce and prevent snail invasions by considerably reducing fish stock and food amount. Best regards sera GmbH Dr. Bodo Schnell
Is gravel with 3 - 6 mm grain size suitable?
Hello, this is not entirely optimal. Food and fish waste remainders easily sink between the relatively large "pebbles". As far as the food is concerned, it is not accessible for the fish any more, and both lead to the bottom ground becoming "sticky" more quickly. Furthermore, such coarse gravel is not quite suitable for fish that dig in the ground (e.g. Corydoras catfish, many loaches etc
Which preconditions are required for Fighting Fish?

Best regards sera GmbH Dr. Bodo Schnell
How large does an aquaterrarium for terrapins have to be, and what do I have to consider when setting it up?
Juveniles of course require less space, but especially terrapins grow very quickly. Concerning "food": sera reptil Professional Carnivor as well as all Raffy types from our range are suitable, except sera Raffy Vital - this is for tortoises. You can additionally give them freeze dried food organisms such as sera FD Tubifex or sera FD Artemia Shrimps as a treat. Concerning...

Some details about the mentioned items: Fish : no fish has any disadvantages, but many will benefit from advantages (all species that search for food at/in the bottom or temporarily burrow into it). Plants : there are no disadvantages, provided you make sure the water circulation within the bottom ground is not inhibited too...
Jumping animals on the water surface / Springtails (Collembola)
Hello, these for sure are springtails (Collembola). They are very common (for instance, they can also frequently be found in flowerpots) and entirely harmless. They even serve as live food for some fish that live close to the surface. There is no reason to combat them. Best regards sera GmbH Dr. Bodo Schnell

Loricariids eat plants
Hello, this is going to be difficult once the Ancistrus found out they like the - apparently very tasty - Echinodorus . You can try herbal food tablets (sera Spirulina Tabs) or sera Catfish Chips, but sometimes this will not stop the Ancistrus eating fresh Echinodorus . In such cases it is better to do without the Echinodorus and use other plant species instead. ...

water. The agent nifurpirinol, used in sera baktopur direct, is also included in sera bakto Tabs. The difference is that sera baktopur direct is dissolved in water whereas sera bakto Tabs are food tablets containing the agent. Best regards sera GmbH Dr. Bodo Schnell
Discus and Altum angelfish together?
Hello, this is indeed possible with juvenile or half grown fish if you leave out the shrimps (which would otherwise end up as fish food sooner or later). But with the remaining stock it is likely that it will exceed the capacity of the tank (see below, please). I expect serious problems with tank sizes below 2 meters, especially if several pairs are breeding at the same time. However, I...
How can I hibernate goldfish living in a pond indoors?
temperatures inside the house (including the basement) are higher, so the fish will not rest but remain active. This does not harm the fish, they do not need to hibernate. However, they regularly need food (e.g. sera Goldy Gran) if they are still active. Temperatures between 10 - 18°C (50 - 64°F) are perfectly OK. You should by all means provide good water agitation and abundant partial...
Neolamprologus brichardi offspring / Does Synodontis petricola show cuckoo behavior?
Hello, Concerning "feeding fry": The fry can soon get the "entirely normal" food - small particles are of course easier to eat. sera Vipagran Baby is particularly well suited. Concerning "fish stock": Just leave the catfish in the tank - even if it sounds hard: a certain reduction of fry numbers is not too bad. N. brichardi is unbelievably productive, and it is...
General information about Bumblebee Gobies (Brachygobius xanthozonus)

They often do not accept dry food − however you can try sera Vipagran or soaked sera marin Granules. Concerning "Betta": this is not very likely, but the gobies are not very suitable for keeping together with...
Combat snails with pufferfish?
pufferfish as "snail killers". It is of course correct that pufferfish considerably decimate snails and usually eat an aquarium snail free quickly, but what happens next? The fish require hard shelled food so they can grind down their "teeth" (better: dental ridge), just as is the case with rodents. Otherwise they will continue to grow until the fish cannot eat at all anymore. Sometimes it...
Which are suitable sand grain sizes?
snails in both cases. Concerning "rotting sludge": quite on the contrary: The risk is considerably lower than in case of coarser material, because organic matter (e.g. possibly uneaten food) does not sink into the gravel and rot at all (this is how rotting sludge forms) but remains at the surface. The above mentioned trumpet snails furthermore loosen the bottom, thus reducing...
Which crabs are suitable for aquariums?
aquarium must be covered so they cannot escape - the crabs are good climbers! Feeding is not a problem, sera Crabs Natural is perfectly suited. The animals will also eat all common types of fish food (especially tablets) such as sera O-Nip, sera Spirulina Tabs or sera Viformo. Best regards sera GmbH Dr. Bodo Schnell
Fish as snail removers?
It usually concerns Clown Loaches and various pufferfish species. These fish are entirely unsuitable for aquariums of this size and/or with this fish stock. Above all, you should reduce the food amount in case snails take over. Snail pests are almost always the result of feeding too generously. You can collect the snails or siphon them off. It is important to remove every snail...
Plants do not grow but dissolve
Possibly high nitrate and phosphate levels (-> lower fish stock, intensify water changes) Unsuitable light (-> improve) Too dense or sticky bottom gravel Coarse gravel clogged by uneaten food, and is not well suited for plants anyway (it is much more difficult for them to grow roots in coarse gravel than in finer gravel or sand) NO 2 = 0.3 mg/l (ppm) If that is...
What to do in case of brush algae?
do not look red), it is important to control the phosphate level as well as the iron level if it is too high. You can achieve nutrient reduction by reducing the number of fish and the food amount abundantly adding fast growing plants generous partial water changes with water low in nitrate and phosphate (!) possibly using a denitrifying slow flux filter especially
White worms in the aquarium
especially their eggs are very resistant. However, you can fairly well diminish their number by siphoning off as many as possible during water changes, by feeding sparingly and by conducting several day food intermissions from time to time, so the fish may reduce the numbers.

Problematic fish stock / Can fry stay with their parents?
A single Angelfish pair easily requires 200 - 300 liters (44 - 66 US gal.) for themselves when defending a territory, and the smaller fish (Harlequin Rasboras!) will sooner or later end up as food for other fish if they do net get caught in the crossfire of territorial fights before. Concerning "rearing tank": This fish stock is already very problematic in itself, see above....
Shell dwelling cichlids have become more aggressive
resources. Sandy bottom does not provide geologically formed shelters such as rock crevices etc. (the fish have taken to retreating into empty snail shells). Furthermore, there is usually rather little food available. They therefore need to defend their occupied territories - and they do so vehemently, even against physically considerably superior fish. Outside courtship/when caring for...
