Pictus Cats

They will eat what till fit in their mouths. They need territory and a hidey hole of their own, so if your tank is bottom heavy than you may have problems. They feed very aggressively and may startle your other fish. I think they are suitable as long as your tank can handle them (size, territory) and your other fish are tough and can fend for themselves.
 
Agreed that they can be a little tough, they will eat very small fish when they need to, but are more opportunistic feeder than a die hard predator. I have kept them with fish as small as adult guppies without problems, any thing smaller and I would worry. Likewise it is important to make sure you feed them their share. if they get hungry they will do what it takes to survive an can eat a fish 1/3 their size. As said they like some space and places to hide, and they do get 6+ inches long. If they don't have a comfortable place to hide they will eventually succomb to stress or related illness.

Thanks , do you think a 30 gal. with some caves and some driftwood would house them nicely ? my 30 gal. long is fishless cycling and iam trying to get some idea of some active fish i was thinking a couple zebras and a pictus cat and some others yet to come , i saw some at my lfs and they seemed very active .. any ideas on any other fish i would be able to put in my tank that are active id really like one of these guys though, please give me your suggestions !

Thanks, Davey
 
I think one may be pushing it for a 30g, its a little tight.
I have two in my 55g. They are always chumming out together. They do this wierd dance. It looks like they're sniffing out each others rear end, kind of like what dogs do when they first meet each other. They also play follow the leader a lot. Its to my knowledge that they are more active in small groups (like 3). Well, not to say one won't be active, but a small group, given that they are comfortable in their tank, will socialize more.

I think a 30 g would be pushing things when they grow up. given that it is a long tank, they might be OK, if you stocked lightly otherwise. Not sure if I'd try two in a tank that small though.

As far as the groups, I've had singles and groups, and depending on the individual, they seem to enjoy life either way. They are also different with their activity depending on individuals. I have had singles that cruised all day, and have had them that wouldn't come out except at night. Seems like I never get two with the same personality. They all like somewhere to hide when they want to rest though.
