I will start out this thread with the second predatory fish that I plan to get ( the other one is an arrowana). I will continue with the tradition of getting a moderately planted tank in my 60 gallon for this. I think this will be great for the piranhas to swim in. Anyways, I haven't taken care of piranhas for like 15 years but now I am back into it again. The only problem is that my LFS sells only a greyish appearing piranha instead of the red belly piranha. Anybody have any idea what's the most common fish store piranha that is grey excluding the red belly piranha of course. I don't even know what the name of this type of piranha is and it seems my LFS doesn't either other than telling me to put a 10 dollar deposit per 1 1/2 inch fish before he sells it to me. He has to sell it to me under the table because it's kinda illegal here. (woops)
