Hi,
I just bought a black pirhana (3-4 in) 2 days ago. It doesn't eat anything and rarely swims around. I put 2 small feeder fish in the tank (25 gal) and it doesn't even go for them. I bought them at a fish store and they had it in a tank with about 8 red pirhana's. The clerk did a demo with feeder fish and they went crazy and ate them all in 2 seconds. I was wondering if you could tell me some conditions that are manditory for black pirhana's to thrive in. Thank you
Matt
Oh yea! My alltime fav piranha! Serrasalmus Rhombeus.
It's only been 2 days. Give him more time to become adjusted. The reason he was aggro at the lfs was because it was his tank. You too khim out of that environment. he has no idea whatsoever if there's going to be some bigger and badder fish just around the corner to come and eat him up yet if he's out and swimming around. I know it sounds weird because
we know there are glass boundaries but liken it to us being suddenly transported to some other Universe in an instant and you might understand. Trust me, within the week at the most he'll be out and kicking bootie! Infact, in about 2 months you'll wish he wasn't so outgoing because he'll most likely rip you apart or at least challenge you when you want to clean your tank. You have to really know his traits to get around that and learn by the ay he leans, moves etc if he means to attack and bite or do a "flyby". You'll learn very fast or lose fingers and chunks of limbs. A Rhom isn't best for trial and error into learning the facets of the piranha world but they are the best p's there are, imo!
These guys are solitary fish. They are not shoaling like rbp's. They are extremely aggro against all fish whether it be a catfish, a totally different shaped fish and even it's own. Nothing can be kept with him for long w/o him killing them. And trust me, he will kill anything you try putting in that tank with him.
A beautiful fish and one I highly recommend.
If you need any more info please let us know.
I'll move this out of the Newbie forum so others can help you also.
