My son has one and i love it. I've been afraid of the same thing. I would love to get one if i thought it would be safeVery cool. I have always wanted one of these. Just worried it would die someday and crash my tank.
Thank you! I love a good challenge. The biggest problem with them is finding a spot where they are comfortable and then feeding a quality phyto. If they are not happy then they blow themselves up into a big ball and float and roll around until they find their spot. Typically that is when they get into trouble.Thats pretty cool that you have more than one and they are rescues! I may break down and get on one day. Though, I must say that your entire system is simply awesome.
