My little shark did finally get more aggressive towards the albino cories and then turned on the hatchetfish who he had previously ignored. The best I could do for now was to give him a 10 gal which is too small, I know. I did have some zebra danios and my swordtail in there so I put them all in with the hatchets and catfish in the 16 gal where the rainbow had been.

The shark has grown but is still quite small, maybe 3 1/2 in. You can see him peeking out of his cave in the bottom right hand corner of the picture. So I think this will be a suitable arrangement for now--he has settled in nicely and seems quite content. The problem is I'm not sure if I can get a larger tank anytime soon due to space/time/finanancial constraints. I already have 6 tanks set up and more fish than I need.

Thats a strange thing about red tails and or rainbow sharks. You can get some that are no problem at all, but I think that you have to find the correct setup for them. i.e. a larger tank with plenty of hiding places. Nice fish though

Sharks used to be my thing until I got hooked on cats.

I had a Black Shark that did nothing but hide behind the tank heater for about 2 months. Then when he got a little bigger, he attacked one of my schwartzi's, wounding it to the point where I couldn't save him. I moved him to his own 20L gal after that and gave him plenty of plants, wood, and caves to hide and play around. He was fine for about 6 months, until he outgrew the tank, at which point I gave him to a nearby vet office that had a large 150 gal aggressive fish tank.

I think you should be okay for a month with a Rainbow shark, but I would definitely think about something in a 20-30 gal size minimum. You could add a couple of semi-aggressives if you are worried about such a large tank for just one fish. Just make sure they are the same size or bigger. (I had a trio of Bala's mixed with a Redshark in a 29Gal that got along fine).
