During my battle with Ich, i killed my two smallest clown loaches with a heater/circulator pump. First one swam up the intake hose and to make sure it didn't happen again, i covered the intake hose with thin sponge filter mesh held on with a hose clamp. Unfortunately there wasn't enough flow, so I started cutting little holes and slits in the material to increase the turnover. He also got sucked up and I found him in the pump... I was so upset that i was trying so hard to help them but they kept dying, and in those two's case directly because of my mistakes.
cleaned my tank, then notcied the next few days he developed pop eye and bloat. Qt'd him in a 50 gallon, 3 days into qt, he decided to blast thru my plexi lid and i woke up found the lid on the ground...and dempsey was nowehere to be found:S
