I'm new to puffers and, when I first set the tank up, I used white play sand. It's terrible. Shows everything and I never can get it to look nice. It's a pain to try to gravel vac also. I'm tired of the tank looking awful so I'm going today to find some new substrate. The tank is somewhat planted but, they're not doing well. That could be due to the crappy light (shouldn't have trusted the petco guy) but, the sand is probably playing a part in that also. Any suggestions? Can I get a small gravel or is that a problem for the puffers?
