I havea 180 with 5 datnoids in it, is there any characins that can live in my tank with a lifespan of at least 5+ ? I thought bout a red tail tat, but apparently those only live 2 years. I just don't wanna waste my money on a 2 year fish.
 
I don't know a red tail tat. You could try any one of the silver dollar species, but all those fish including the Datnoids will outgrow that tank.
 
id go with either a small species of atf such as a forskahlii. they max out around 18" and are slow growing. definitely live more then 2 years. if u dont like them then u could try yellowtail cudas or odoe pike. im not exactly sure how long these guys last but i know its more then 2 yrs.
 
I would start off with some "hardy characins." Wolffish seems to be a good fish for you. They are not finicky fish and could be quite forgiving. They are very tough fish if you give them the right requirements. IMO, the payara and ATFs are more for the experienced fishkeepers because they can end up badly from a keeper's mistake. These are not forgiving fish. Especially for payaras, they are quite sensitive fish if you don't know the specific requirements.
 
Maybe a large specie of Silver Dollar:). Had mine well over five years, going on nine!

tgroen, ur a freakin genius. the FATF seems like a perfect tank mate. I never thought any tigerfish species could fit in a 180.
 
I could be wrong but I'm not pretty sure about Red tail Payara lifespan', but two years seems to be to few for that kind of fish. I think that we have no data about they lifespans and this 2 years number is based in (probably) survival record wich is very different from lifespan.

Red tail payaras don't seems to have a notably high metabolism at least when compared to other characins (sister groups like acestrorhynchus), they don't seems to grow fast or other traits related to short lifespan fishes and personally I can't find any short lifespan predictors in they biology, of course that I'm talking this without any scientific support but I don't think that any lifespan comment about red tail payara is also non-scientific.

By the way....Fatf is a awesome fish!

See I always thought payaras in general had short life spans, I made a thread bout red tail tats life spans and the consensus seemed to be 2 years. I really only like to have fish that can live 5+ years. im on my search for a FATF now.

Yes. I saw that thread...I just don't agree. I don't think that we can conclude nothing about the lifespan of these fishes based in a few cases. Probably (IMHO) we aren't keeping these fishes correctly if they are living so short lifes. Short lifespans are almost always related to very high metabolic rates, high grow rates and early reproductive span, and to be honest even smaller chracins can leave longer than this. I just can't see any of these points in Hydrolycus tatauaia.


Again...I could be wrong.

i think, as touched upon, survival time is very different to lifespan - i also agree with the comment about these fish being less forgiving and that's why it's commonly said that one has died when not very old.

To repeat what was already said, but hopefully to reinforce the comment, i agree that a wolf might be more forgiving and perhaps a better choice of fish.
