So let me start by saying: I've only been keeping fish for a little over a year, and I am learning, but there is SO MUCH to learn. I currently have a 20 gallon tank with 6 glo tetras, I had a glo shark and Chinese Algae Eater but this morning they were both dead. From what I've tried to learn the Golden Chinese Algae Eater could have sucked the sharks slime coating off, he was fine until I introduced the GCAE. But my tank has is starting to get Algae on the glass and plants and decor so I wanted an Algae eating helper in the tank, what's the best thing to get that won't eat my fish? my kids and husband are not happy?
