Jake, I'm sorry your histys were jumpers. Mine were not.
The bad thing for me was 1 liked to "hide" in the powerhead outlet. It's tail was "always" visible...until I tried to clean the PH. No tail showing but I still tried to shake/wash him out if he was in there. Took the PH to the sink to clean & OMG! he went down the garbaga disposal! I have skinny hands & could reach in & grab him. I put him back, but a few weeks later 1 died (sniff). I assume it was the PH/disposal loach. No other fish were effected thank goodness.
Mine were very day active & people interactive, maxing out at 4+ inches. I would love to keep them again!
