Hiya, I'm thinking of buying a 130L (34 gallons) Aqua One 620T tank (tall). Would I be able to stock it with:8 neon tetra8 black widow tetra8 penguin tetra(and possibly) 3 albino corycatsI've heard that black widow tetras can be aggressive so I'm not sure whether to purchase them. I hate it when my fishies don't get along I know that the tetras are all schooling fish and need at least 5-6, but I like how they look in groups of 8 personally. Not sure whether the albino corycats would be pushing the stocking a bit too much? Think my combinations should be okay though because neon tetras hang around the middle to bottom, corycats are bottom feeders and apparently black widow tetras hang around the middle to top and penguin tetras hang around the top? Covers all the stratas well so they might not get in each other's way too much. I love kuhli loaches too, but I already have the corycats and having both would definitely be pushing it and the footprint of the tank isn't very large. Any second opinions? Maybe suggestions? I do have a lot of tetras going on in there, any suggestions as to maybe different fish you like better that you'd rather put in there? I've had bad experiences with gouramis in the past... but maybe I could just get like one neon dwarf or something?
