I currently have 3 platies in a 10 gallon tank that I am giving to a friend tomorrow.
I want to get a dwarf puffer or two for the 10 gallon. Do I have to do anything to clean the tank between fish? I will do a water change but should I vigorously clean the gravel or anything? It may be a stupid question but I was thinking about it earlier... The tank is cycled and everything. According to my research the tank conditions are good for a dwarf puffer.
AND are Figure eight puffers freshwater or brackish?
