Do you know your parameters? Did you cycle your tank before adding fish? There are many factors that could be involved here.
It was QT tank - 5 gal tote with lid. I put in a heater and a sponge filter that usually was in the main tank (in addition to my canister and HOB). Whenever I buy new fish and start a QT I use this sponge filter - instant cycle..... Plus, I change water every other day (at worst every 2 days) in the QT for 2 wks....
Still kind of puzzled, because after first 4 days or so I only saw 5 of them. I should have taken decorations and things out and inspected right away.... I just assumed he hiding.... Thanks for the replies....
