I have decided that I need a snail to help control algae in my 6 gallon betta tank. As much as I clean the algae off, it’s hard to get into crevices on my rocks and some areas of the glass. I was looking at nerite snails since their eggs don’t hatch in freshwater, and I came across a red racer nerite snail. Unfortunately, everywhere I look, they seem to be sold out. I just need one or two. Anyone know where I can get these?
