I lost 2 clown loaches yesterday. They were both new to the tank... about 2 weeks old....2" in size. I have plenty of rock set up for cover, several plants and other fish in the tank. The loaches were the only ones Affected. Temp stays at 78-80 with under gravel and top filters and a 7 ph. After reading several threads here... I removed all carbon from filters and treated the tank with "Quick Cure" at about 1/2 required dose. Both loaches went into an immediate frenzy for about 2-3 minutes...it seemed like i poisoned them... swimming and shuddering all over the tank. Then they laid about with very little movement but seemed to be breathing fine... gills were moving.. and upright. I found them both dead this morning. Could it have been something other then "ick”? Looked like ick, acted like ick, but treatment had a very bad effect. Any Ideas before I replace these loaches???? AGAIN no other fish were affected.

Thanks
I guess I'm not the #1 daddy anymore.
