came to my tank to find my 6 month old cleaner shrimp dead and my green BTA lying on the sand floor. i fed the anenome yesterday and both animal looked great. can i save the BTA? its tentacles still have color but it wont attach to any rock. what am i doing wrong? my nitrates are high but my cleaner has been through an entire tank apocolypse and seen it out. please help me, these continous problems are really beginning to ruin the hobby for me.
