Hi there- Some of you may know I like my shrimp and I like my dwarf cichlids, which leads me to some shrimp only tanks (just doing small tanks right now, I have been successful with dwarf cichlids and shrimp in a 55. Doesn't work for me in a 20). Sooooo.....Planaria is not new to me. I usually manage planaria situations in small shrimp only tanks through daily manual removal. I returned from vacation to a planaria outbreak (yes, I am an over feeder. No, they were not over fed for the month we were gone, but the darn things reproduce like crazy). Generally, my neos can out breed these nasty buggers until I can get it under control, but my caridina cannot. Not a baby survives, and the adult population dwindles. Research is suggesting Panacur C (a common over the counter dog dewormer) as a shrimp safe immediate planaria (and hydra) killer (some risk to snails). Something not suggested when I did shrimp before. Anyone try this? Thoughts? Not concerned about plants. Not concerned about snails. Have also considered adding an australe pair...or some other fish that has ignored shrimp in my experience. Will probably buy a more expensive product recommended and used by a friend ( SOBAKEN Genchem No Planaria Shrimp Safe Planaria Hydra Killer Shrimp Fish Planted Tank) , but I am intrigued. Anyone up for discussion?
