That's the exact type of driftwood cat I was referring to!
Mine almost never came out unless all the lights were off though, and only got to 3 1/2" (got him from someone else though - he may have been stunted). So we only viewed him under the moonlight. But as soon as the lights went off he was out swimming around midwater, just like a shark.
Really neat little guys. And somehow always fat even though we rarely saw him come out to eat.
you had only one?...that might be why you never seen yours they love to school..I had two and was forced to re home them ..but the girl i have them two already have two.
with only two they would swim together in a school all over the tank with lights one...in the group they are amazing!..crazy cool to watch and feeding time is like a shark frenzy!!
with me (male and female)
and with the new owner...bed time
