So, Snail infestation in my 20g. I have two dozen RCS, 5 are berried, happily expecting. What can I safely use to kill these snails? Assassin snails will eat RCS shrimp?.. C. Loaches will eat RCS?.. I really dont want to tear my tank apart. Will be checking filter for eggs. Can I safely squash eggs if I find them? We picked out 3-4 dozen snails. MTS and Ramshorn I think, possibly bladder/pond, who knows. Only visualize a few tiny ones now.
