Thanks for your feedback Soyadude. I think you are right about the rams... I have yet to keep one that lasts over a year. I applied the "dun care" technique and basically, those strong enough to survive are worth me keeping them. My mollies seem to be okay with this rule but not the rams. Having said that, whether I try to help it (with medicines) or let it heal itself, none of my sick rams have successfully recovered.... yet.
