On a positive note... The male lyretail, that's been covered with excess slime and had a slight case of popeye, seems to be much better. I purchased a cleaner shrimp a few days back. The lyretail wouldn't leave the shrimp for the first three days. He started venturing out yesterday, and today he looks spotless. I still can't get him to eat though. I've even tried new born minnows. He bites, and kills them, then just spits them back out.
