Questions How does the checker decide? It runs the same tank model as the planner, both ways: can one eat the other (mouth size against body depth), does one nip long fins, do their temperaments and territories clash, and do their temperature, pH and hardness ranges overlap. Keeper reports add clashes the rules miss.
Two species are compatible. Will they be fine in my tank? Only if the tank is big enough for both groups and the water suits both. Add them to your own tank to check size, load and every other inhabitant.
