My tank 14 gal peninsula about 1 year old. 8 pounds of rock 6 pounds of rock were live rock and the rest were dry. Live sand about 3/4-1in sand. Have only carbon and gfo with media and hd prime 10 hour about 20% on uv blues and 10% on white. So I pick this rbta about 2 weeks ago. Right before putting it in I did a water change( I do about 4 gallons)( I buy my ro water 0pp) so I like to run my tank at 1.026 sal. He was was fine and was moving around till he found he’s spot two days later. Maybe two days later I see it tucked in with slime and I read that he was just expelling his waste didn’t worry but now in the mornings he’s tucked in with his mouth open I don’t see slime anymore. I did notice by its food some brown stuff. This is my first salt water tank and my first ane. I don’t care loose what I spent. But I do care about his health and the health of all my living creatures I have in my little tank. I have 2 clowns 5 herm 2mex turbo and 2 naserious snails. I check nitrite and nitrate are at 0 and ammonia was 0. Only thing ph might be at 8.0 so I added marine buffer 8.3 and lower the salinity to 1.024
