I have a 25gal planted tank. In there are some tetras, pleco, ghost knifefish, and small angelfish.
Next i have 55gal with some plants. I have silver arowana, redbelly pacu, clown knifefish, oscar, redtail catfish, severum, and large pleco. For now they are all good together and are still small so dont worry about space.
Im going to get 200+ soon. :)
Rest of Your Aquariums:
I don't have more aquariums than that/those described above.
