Just got back from work and i find this. I noticed a small white wound on the star about a week ago but i thought its just an abrasion from the rock. Salinity is at 34 ppm but it has been this way for months now. Im increasing it very slowly. No other animals in the tank besides the snails and cleaner shrimp. I feed the tank a protein based and an algae based food 2-5 times a week. What could be the cause?
Tank is a 3 gal bowl. 4 months old. No fish. Sofites and inverts only.
Really devastated to see this, he was one of my favourite creatures. I think he will be dead before the end of the day...
