I will definitely not do anything major before heading out again. I may have caused some movement of some stuff in the sand...but unlikely. The tank is a 47 gallon that is 31 inches deep. Before anyone says anything about being overpopulation. I was constantly checking chemistry and the levels were fine. there were only a couple them that were larger...most were smaller juveniles. I had so many in the tank because I was going to take some out after I had confirmed the sexes of them...my intentions are to breed them, so I wanted to make sure that I had the right numbers of males and females. The jevuniles are hard to sex, so I overbought just to make sure. I had scrapped the glass regularly without any difficulties in the past... The tank had been up and going since christmas. OCDP The heat wasn't a concern. This happened after the big heat wave. One thing is for sure...I have also learnt don't have so many eggs in one basket so to speak. I will be breaking the numbers down into a couple of different seahorse tanks in the future..so that I don't have so huge losses if, god forbid, something happens again in the future.

Sorry to hear about your SHs, Neal
 I suspect it may have been the algae you scraped off the back of the tank. Was any of the algae red and stuck on like coralline, but not coralline? I had some of that stuff on the back of our 120g last summer. I didn't know what it was, but it was overtaking the coralline, so I scraped some of it off. Was away from the tank for 3-4 hours only to come back to two dead fish - my favourite ones! - and the others gasping for breath. Did a 40g water change and threw in some carbon right away, which saved the remaining fish. What was the red algae on the back of the tank? Don't really know, but I'm guessing it was a species of cyano that, when disturbed, released a cr*pload of toxins. Corals were not affected.

the algae was a cyano like substance...perhaps that explains what happened.
