I've never owned a tank this big. I am literally in awe. Because of this I am completely clueless. I only know my nanofish. chili rasboras, least killifish, pea puffers... these are the species I know. But I want to do something totally different with this tank!! I think... The idea of 20+ chili rasboras for this giant tank is seriously tempting. Lol. The tank is not up and running yet, as I just got it today as a gift (thanks babe). I had to order a stand for it because nothing in my house is strong enough to support it. So while I wait for that to come in, I wanted to get ideas on species. I will be moving my 6 kuhli loaches to the 37 gallon tank. Or I think anyways. I don't necessarily need to..... Oh goodness. I'm just completely at a loss right now. What are your favorite species for a tank of this size? I should mention the tank is taller than it is longer. 30 in L x 12 in W x 22 in H are the measurements. What are some good schooling fish or pairs that could work for the upper level of the tank? Any other species you might suggest? I think it would be cool to do one of the three ideas: 1) A pair of fish, A mid swim level school, and my kuhlis/something else on the bottom. 2) Just some giant schools of nanofish 3) Only a couple of large, oddball/rare species. Thoughts?
