I've read a lot of stock idea forums, but wanted to get your thoughts on what I'm looking for. I'm just about ready to cycle my 55gal (see image) and I'd ideally like to get a semi-aggressive tank going. The temp is 78°, but I don't mind slightly changing it if I need to. I was thinking about getting a solid group of tiger barbs, maybe 15 or so, and some compatible fish to go with them. Maybe a red tail black shark? That and some type of catfish for the bottom. Any ideas of how I can achieve this or any other possible combos?
