For some strange reason, the other day all my glass fish died in two hours. :'( The few days before, they looked like they had a little bit of ick, so I treated it with some fish treatment (which died all the sealant blue) and it looked like it went away. They were fine for a few hours, but then one started acting weird. It kept tipping forward, like it had swim bladder disease, but it was to late to go to the store for treatment, so I went to bed hoping it would get better. The next morning it was dead with it's head pointed into the gravel. Within the next 2 hours, I watched the other 2 fall forward and swim with thier tail pointing up until they both stuck thier heads in the gravel, just like the other one. Does anyone know what was wrong? Was it swim bladder? How do I prevent whatever it was? Oh, yeah, forgot to say, the barbs were ine, and don't seem to be getting sick. Weird, huh?
