I plan on upgrading to a 180 gallon 100% forsure so my leopard ctenopoma can "roam" when I move out of my parent's home but school is taking me 3 more years to complete. I feel a little guilty keeping the leopard ctenopoma in a 40 breeder for 3 more years. Do you guys think it's okay since they grow slow and ill upgrade in a few years? It is around 4 inches now. I really like it because it knows when I reach into my cabinet to get food to feed it and wags back and forth underneath the feeding ring which I find cute/awesome....
