My setosa has been acting up for about a month or so now. I don’t want it to die. It started in the middle of the tank, I moved it up when it start ed getting white in fear that it wasn’t getting enough light. Then it got worse so I moved it all the way down. It kept going white. I moved it under a rock, all it did was get some detritus on it. Now I moved it back up. Help me. I tried feeding it today too btw.
