How large do Ancistrus catfish grow?
I have the well known Ancistrus catfish in a 240 liter aquarium. The male is 13 cm long, the females about 9 cm. How long can they get at the maximum?
this is not entirely precisely predictable, because the common Ancistrus catfish very likely comprise several hybrids. Some of them grow to only about 7 cm, whereas others grow to about 16 cm.
