Yes it happened to me. Mid december i Convinced my wife to let me upgrade from a 46 Bow to a 90 gallon. On January 21st at 1:00 in the morning i woke up to hear water running i got up to find my new 90 gallon had sprung leaks on the front two corners of the tank and in the middle on the back water was coming from the bottom frame of the tank. A quarter of the water was gone and had to rush to try and get water out two clowns, catalina goby and midas blenny. I put everything in buckets including the rock with water and was only able to pull out the clowns could not find the blenny or goby. The LFSe gave me a new tank which i set up again put rocks back and to my surprise the blenny and the goby where in the rocks hiding out. they survived with no heat or food in cold water for about a week. so i guess no lossess other than pissing off the neighbor below me i live in a third floor Apt. New tank seems fine begginning cycle again. Just wanted to share since i can finally speak about it.
