i know this is a bad idea

but i will be adding a small rainbow shark to my tank for a little while (a friend needs it out of his current tank and is in the process of getting a larger one). will the shark and my common pleco (5 inches) be too hard on each other? i've got a cave i'm going to put on the other end of the tank from the pleco's favorite rock for the shark. also, i have swordtails and tiger barbs: are any of them likely to be harassed too much in the short time the shark will be with them?

my friend is having problems with the shark killing his bloodfin tetras (his tank is too small, again the pet store people weren't as helpful as they needed to be).

I had rainbow sharks and tiger barbs and a pleco together and never had a problem. I'm surprized the swordtails are okay with the barbs in my experience tiger barbs tend to nip fins.

My rainbow shark, corys, zebra danios, and cichlids all get together in a 20 gallon...it really depends on the temperament of the shark. Mine is reaching 3 inches and is relatively docile.

My RTS was far more hostile when he was in a 10g tank.

i have 9 barbs, and apparently that is enough to keep them happy. they haven't bothered my swords at all. i'm mainly concerned because this shark is terrorizing the bloodfins he's currently with, whenever one comes near the bottom he freaks out and chases it. this could be because they are in a 10 gallon tank and there really isn't enough room in there. that is what i'm hoping, at least.

Well he also.has an established territory there, in your tank he wont... the only thing id worry about is him freaking out at thenloss of it, i had a lepronis once who was crazy violent out of no where to fish he shouldnt have cared about, and when i moved him to his own tank he went nutso... oddly enough only when i entered the room.. it was like he had a vendetta against me. But yeah 10gallons is small for a rainbow shark and theyre super territorial when they mature, but in my experience they only really like to pick on each other and fish that look like them.

ok, so the rainbow shark is in my tank, i rearranged the tank to give him hiding places, and my male swordtail is bullying him. kind of backwards of what i was expecting.

so, right before the shark got added to my tank, i added a rock cave and rearranged a lot of my other rocks into cave like things so he could have a choice of where to claim. instead of claiming any of the rock caves on the bottom of the tank, he has claim the space between the heater and the wall of the tank, between the bracket things holding it on. silly fish.

of course, this could be because my male swordtail was a bit of a bully and kept chasing him around. this has calmed down for the most part.
