Columbian Sharks Vs Monos

[jsoutar]

Hi there

I am wondering if anyone can give me some tips as to how I can stop my 3/4 inch mono's (Monodactylus argenteus) from nipping at my 4 inch Columbian Sharks (Arius seemani)?

I have had two columbian sharks for 2.5 months now and added 3 mono's 6 days ago. I am noticing that one of the mono's is picking on one of his own and also nipping on the columbian sharks. They are fed Tetra flakes, blood worms and Shrimp Pellets...Everyone looks healthy and there are lots of hiding spots in my 55 gallon tank...all levels are perfect and no one seems to be picking on the two mollies...any help would be greatly appreciated as I got the tank for the sharks. I have started some Melafix treatment to try and replenish the sharks fins...

Research online is telling me that the sharks should be the aggressive fish in the tank as they are bigger not the little monos?

Please help!

From my experience columbian sharks are not aggressive and can easly be bullied. They will however eat anything that they can fit in there mouths. What I would suggest is removing the problem.

I noticed that you have to columbian sharks as well... do any fish work well with these sharks?

I have got mollies, swordtails, clown barbs, bala sharks and tiger barbs with mine, they all get on well with each other, the bala sharks seem to school with me catfish and even seem to playfuly chase each other now and again...

I have loads of hiding places (vegitation) and plenty of free swim fr them, it seems to keep them happier...

You do know columbians are brackish right? Many of those fish that you mention you have with yours are not brackish.
