Geo Sveni tankmates

[jandb]

Hello, I have a 96x30x24 high 300 gallon with 10 adult svenis. I started off with the same number red back scalare a couple years back but am down to 3. The geos don't pick on them they're just getting old. I'm looking for something towards the top of the water column to complement the geos. First I was thinking of a school of larger tetras, but I'm not sure what kind then I thought maybe a black arowana. Does anyone have any thoughts?

Personally I think the black arowana is a bad idea. Not only does it get too big for that tank (a 90-120 cm fish is not going to have an awful lot of space in a 244 cm long and 76 cm wide tank), it would be dropeye-prone because of the bottom-dwelling eartheaters and could possibly eat the eartheaters too.

African butterflyfish or pink tail chalceus could be some alternatives.

I appreciate the advice. I'd like to keep the tank south american and would like a school that goes back and forth. Any thoughts there? I've had pink chalceus before and although I liked them they weren't real active.

Glad I could help.
If you want a more active, schooling back and forth top dweller from South America, you might try silver dollars (and you have a couple different choices with all the varieties like red hook and blackberry).

They're both cool but unfortunately I've kept both and would like to try something different and not as big with more of a slender shape. I like how chalceus look but want something that will school up and go back and forth.

South American, slender, schooling fish that are top swimmers and will actively swim back and forth.

The best thing I can think of that fits is the red tail hemiodus. If that still doesn't fill the bill (I know how it is, I had to eliminate lots of options before settling on some of the top dwellers for my future loach tank!), I'll see what others suggest.

I agree with you on this one. I think they're closest to what I'm looking for. They do have the kind of school, sit and twitch like the clalceus more than I'd like but they are cool. I'm trying to think of a longer, deeper bodied tetra, not a silver dollar, that schools up nice. I'm at a loss.

maybe some of the oddball Leporinus species? I had good luck with Geos and Red Banded Leporinus in a 125 and a friend keeps 8 red head Tapajos in a 300 with 6 Leporinus sp. "strawberry" . Both combos work well with smaller tetras and catfish with no issues.

There’s tons of tetras from South America but a group of congo tetras or rainbowfish would great even if they’re not the same biotope

Those are super cool. I just looked them up. Not cheap but real neat.
