I've been away on business for two weeks. Put my light on a timer. And got a couple medicine organizers to sort out the right amount of food and treat rations. I came back to a sad tank. My black Molly has Dropsy. A pretty bad case, so I went and got some Tetra Fungus Guard. Unfortunately I don't have another tank to quarantine him in. So I treated the whole tank. He seems to be the only one infected. I lowered the water level and took out the filter cartridge. Hopefully the heavier water flow will help. Any tips or tricks? Unfortunately I leave again on Sunday for another two weeks. I miss my fish! And I'm afraid I'll come back to a worse situation.
