hey yall just got back from a no internet vacation of 8 days, got back last night turned on my skimmer in the 40 and hit the hay. woke up today looked over only saw 3 fish, i was still sleepy went back to sleep, woke up about 10 mins later looked at my tank and ONLY SAW 3 FISH!!! i had 4 when i left, wanna guess which one i diddnt see................ the ATLANTIC BLUE TANG, i legit cried for a few mins, so i started to look everywhere nothing, and he diddnt jump out if i cerwan wrapped the whole tank to minimize evaporation. so in conclusion the ABT is gone. but my hippo survived, and 2 chromis they will be the only fish in there for a while. its a sad day.
