I have a hatchling RES (1.5 inches max) in a 10 gallon tank however I couldn't put that much water in (about 4 inches max in there now) because he is still working on his swimming skills/recovering from a bad journey through one illegal seller to the next. Since I don't have that much water in the tank I can't use a cannister filter so I put the air pump in today to at least keep the water moving.
Question: should I keep the bubbler in his tank or is this dangerous and how much water should I have in his tank?
*By bubbler I man a Tetra air pump. Please message me if you can help!
