Thanks for the input. I need something quick, I just added three fish to the tank and one disappeared after doing great after the first day (purple firefish). Anhyhow, I couldn't find it after a couple of days and then I noticed my leather wasn't extending. Then I saw my orange bubble tip was completely shriveled up and it's mouth was protruding slightly. I thought it was the end for him and I was bummed, but I did a 75% water change and several hours later some of the bubbles tips were filled up with water. Long story short, everything started coming back but I can't help but think that a clean up crew would have minimized the damage by consuming most of the waste before it broke down. Hopefully I don't have any more fish loss, but just in case, I think the clean up crew can never hurt.
