Hi All

What an awesome forum. Im sure I will find lots of useful info here and I look forward to watching my fish & plants florish!

However, at the moment I have a small problem. I have a 50ltr tank which is home to an orange gourami, silver shark, orange barb, angel fish and a fiery red tail shark. This shark singles out and relentlessly chases another fish. It is crazy to watch. They bang into the glass walls, the gravel etc and has now started chasing the silver shark which is somewhat bigger. I have already lost 3 tiger barbs to this little aggressive and very cheeky fish!

What are my options here? Is there anything I can do to tame him or should I return him to the aquarium outlet? I have had him for nearly 6mths now and he has grown considerably, as have most of my fish.

Anyway, any suggestions? I would rather not rtn the cheeky shark, but I fear I have no choice....??

Thx heaps guys!!

Hi & Welcome

Redtail & rainbow sharks are always a problem in small tanks. They are vegetarian and protect the territory against all intruders. Unfortunately they think the entire tank is theirs and everybody else should nick off. I would take it back or get a bigger tank to put it in. If you have lots of hiding places (driftwood, plants, etc) it can reduce the aggression.

That's odd, I have no problem with mine! Maybe that is because he is in a 20 gal with a pair of Kribensis!

Also, is the silver shark you're mentioning a bala shark! If so, I belive you've got him in too small of a tank! They grow to a foot long or more.

Maybe get a pair of cichlids to show the redtail who is boss?

Your tank sound cool!

Hi Guys

Thx for ur suggestions....Ill look into them.

Cheers
