Thanks a lot that makes me feel better. I don’t have the deminsions of the refugium yet it is a hang on though. I have switch my sump fuge out for a hang on. Would the pipefish or even the dwarf seahorses live on enriched brine shrimp, because I don’t have the room to keep a constant supply of newly hatched brine. if I went with dwarf seahorses or pipefish what would you suggest the stocking level be?
