I don't know what's wrong with my tank. A couple weeks ago, my cory was stuck to the filter intake. He looked healthy prior to that. Within a couple days, he was dead (after being stuck, he never recovered- unstable, wobbly, weak). Now my new cory (of a few weeks, I bought him just before my other cory got stuck) just got stuck to the intake! Same thing. Now he looks weak and unstable. I don't know what to do for him, I don't think he will last long. Plus, one of my zebra danios, which I've had since March, started acting odd over the last couple weeks. Thin, sluggish, hiding out alone, just not himself. He died this morning. I did have an outbreak of Ich a week and a half ago, but it only showed on my serpae tetra. I treated the tank and got rid of it with no deaths during treatment. My tank is a 20g with an AquaClear150. Ammonia 0, Nitrite 0, Nitrate 5, ph 7.2. Temp. 79F. It's a non-planted tank. In my tank are 2 serpae tetras, 6 neons, 2 strawberry tetras, 2 swordtails, 2 platys and 2 remaining danios. Plus the obviously sick cory. Anyone have any suggestions? Something must be wrong with my tank, but I can't for the life of me figure it out. Thanks!
