Haven't noticed him scraping the rocks etc. Other than the slaughing off of tissue he seems fine. I do dose iodine (lugols) and allow their food (pe mysis) to soak in selcon and vitamine C. The flake food is Formula one. With him only interested in the flake food its been hard to get him to eat enough to gain weight. Ive also tried mysis and brine shrimp but he spits it out. Im probably going to get a small 8 gallon tank or so and put him in there for a while. I should never have sold my biocube 8 !
Thanks for the input guys.
