Wow, what ever sized tank do they need? How big do they actually get?
I guess tank mates are out of the question unless they're food or equally menacing
Thanks.
Yes there are variations in eventual size and compatability with others. The Erythrinus species are small at 8" -10" and can be kept with other fish as long as they are too large to eat and not another Erythrynus. I suspect it would be possible in a very large tank. I have this one in a 5' with a number of other Amazonian fish.
The Brazilian Curupira I have had for about 2 years now has reached 11" and hasn't grown past that. Charactor wise this individual is a no no with other fish. I once tried to compine it with a 13" Fowleri cat and he relentlesly attacked it. Although this fish does have the defining charactors of Curupira I think it may be different.
The Venezualan curupira is widely kept now outside the UK and although the fish is supposed to reach approching 30" it is difficult to get them passed 16" in captivity. There are some exceptions but these have usually been captured already at a large size. I am hoping to do better though. Lots of keepers including myself have been experementing with combining this wolf with other fish and have found that as long as the fish is too big to eat there is no issue. They live in large rivers so I guess territory is not an issue. I have this one with a large ATF, a large Snakehead, Cornish Jack and the intermedius.
The intermedius is a little bit of an unknown. at the moment it's 14" and I suspect it will have have a simaler growth pattern to the other large wolves. at the moment it is in the same 8' as the Curupira.
The aimara is again a large fish, They are suppost to reach 3 to 4 foot, realistically I am expecting 20"+. There are some very large examples 30"+ out there but again these fish have been brought in at the large size. This fish is a definate no no with others, he attacks maintainance equipment. Has had a go at a couple of rocks I have put in aswell. These fish live in rapids and under waterfalls where i guess the perfect rock to ambush prey is limited so requires very aggresive defence to keep ownership of there spot.
