| I use ghost shrimp in my tank. I keep a good supply of them because my angel fish and black ghost knifefish eat them. I buy about a dozen every other week for them. They cost about .36 each. At any time, I may have about 20-30 of these guys running around in my 120 gallon tank. They will keep algae off ornaments and such, but not off glass. I do not find snails very efficient at that anyway. My ottos do a much better job. If you do not like the ghost shrimp, there are other, but more expensive, freshwater shrimp out there too. |
