I got Vladimir 5 weeks ago. His gil was inflamed once I got him home, and I was slightly lax in changing his water. But for the past 14 days I have changed his water ever 2-3 days. He has a 1-gallon tank with a light that I turn on during the day and a heater; the temperature is between 73-75 (I know it should be between 75-80 but I can't find a heater strong enough that will fit in the tank). The pH is fine, and he's eating all the food pellets I give him. He swims up and down and around the tank, swims in the "log" I have for him in his tank and even blows bubbles up to the top to make a nest to mate. He's reactive when I go up to the tank and I use aquarium salt and water conditioner in his new water. Everything is fine with him, except he still has an inflamed gil. And now I think his eyes are beginning to bulge. So I want to get some Ampicillin for him, and my question is - what kind do I get? I was told not to get "BetaFix" because one of the ingredients is bad for fish. I am hoping to get one online, or if you live in San Diego, that's where I live and if you know any good fish stores that sell Ampicillin, I would love to learn of them. I've called a few stores, and none have had Ampicillin please help, poor Vladimir is apparently getting worse.
