Hi! First time here on this forum.
I've got a 2.5 month old cycled 10gal tank. Started with a dwarf gourami, 3 corys, 1 guppy, and 2 ghost shrimp. Just added plants 2-3 weeks ago. Temp 76-77°, PH 7.4
Water parameters are all good, except when I brought water for testing to LFS
, they said I had trace ammonia of 0.25. When I test my water at home it looks between 0 and 0.25. I did an immediate 20% water change. And will do another today. I do a 15-20% water change every week.
Now, my question: I keep losing fish. I just lost my dwarf gourami (stopped eating, dead 3 days later), lost a cory (stopped eating, emaciated, sat at tank bottom, euthanized him 2 weeks into it, no swimming issues), no visible external symptoms besides behavior changes. I did see some shimmying in the DG the day before it died. And one of my false julii corys is swimming frantically, harassing the other one, and seems uncomfortable but still eating.
So, I'm down to two corys, one guppy, and one ghost shrimp. Could I have internal parasites in my tank? No quarantine tank. I have some Imagitarium Parasite and Bacterial infection remedy. But I don't have a separate carbon filter to remove from my hob
Marina Slim 15 filter. It has three one piece, plastic cased filters.
