Eggs or sporangia on Java fern?
Yesterday, I discovered quite a lot of "eggs" on the leaves of a Java fern plant. They are black and about 0.5 mm in diameter. Are they angelfish eggs? I also keep bottom orientated fish whose name I do not know. They are about 4 cm (1.6 in.) long and have a gray/white pattern like a marble table. They are very thin and actually rather nocturnal. Are the eggs theirs?
Hello,
according to the description, I can certainly exclude that these are angelfish eggs - if only because angelfish care for their fry and would guard them.
I also think eggs of the other fish species (possibly "Otocinclus" Midget Sucker Catfish?) are not very likely - the eggs are clear, and one can see the growing larvae in them.
If the black spots are located on the bottom side of the leaves and form a more or less regular pattern they are very likely something completely different: spore cysts (sporangia) of the fern itself!
