algae cleaner with assassin snails
I have a 20 long in which I would like to keep algae under control. I have assassin snails to keep pest snails out, so could i out in some bigger nerites, or would they get eaten. I also thought about ammano shrimp however I have some electric blue rams, The tank is planted, so would the ammanos become food or would they survive. I also have 2 otos but they are not really doing the job right now. Any suggestions?
