It took me months to get a pair to live from petco, I swear I had been through about 20+ rams all dying within a 2-3 days of me having them. I kept returning them and getting more. I knew my water was perfect & the fish just sucked ! none of the lfs by me were getting rams at the time. So I finally ended up with a pair of gold rams that lived a whole week. The female started flashing on everything in the tank she was literally bouncing all over the place.
then finally I got a bottle of quick cure, and a bottle of vitachem and treated the tank non stop. I dosed all their food with vitachem.
Now, I haven't used quick cure in a month or 2, but I still drop the vitachem in the tank & the rams are doing amazingly. I call them gold rams on roids lol, they literally eat their food every day like savages who never saw food before.
I thought they'd be sterile considering where they came from, but to my surprise I've hatched 2 batches of eggs from them. This second hatch much better than the first... until this new problem of them all developing swim bladder issues.
I changed like 1/2 an inch of water out of their 2.5 gallon ! I changed it with water from my 29 gallon with the exact same parameters & a splash of prime just to be safe.
