I have a group of 6 G. Balzani in a 55 gallon tank. They are all pretty small right now. They are terribly skidish and i want to add something to help them relax a bit. The Temp is fairly low at around 72 degrees and I'm planning to start lowering it even more over the next few days. I want something that schools like Tetras, minnows, rainbows etc. Whats a really colorful dither fish that I can add to this tank to get the Balzani to start swimming around the tank more and that can handle the low temps. I saw a post about this a few weeks back but haven't been able to find it.
