2 Tetra left due to disease. What can I do now?
Hi, I'm new here. Great to meet you all ^^
I cycled a 10gal tank and after a water test a few weeks later, bought 5 diamond tetras from a petstore near me. One was smaller and weaker than the others. I thought he was just jossled from the trip. Nope, turns out he had mouth rot or columnaris or something. Long story short, after medications and salt, 2 of the 5 remain. I was told to treat the entire tank instead of quarantine individuals by a lady at a petstore whom I'm not sure I should have listened to.
I'm pretty much brand new to fishkeeping and this was an interesting way to start the hobby. I'm not going to give up but I don't know what to do now. I only have 2 schooling fish which they likely are not fond of. I don't know if the water is clear of the disease. I don't know if I can ever put other fish with them or risk the issue over again. I don't know if they're healthy now even though they look it (more or less).
The water parameters seem ok. I wanted to return the fish but they wouldn't accept them since the issue didn't show up right away other than the little fish acting more tired than the others. Distinctive symptoms showed up after about a week, a day after the 2nd water change. Before that, the fish seemed to be ok other than being a little more standoffish with the others which I should have found odd.
If the remaining die too, what do I do with my plants? Is there a way to know if the disease is clear? One appears to have no symptoms, the other has consistently minimal symptoms for a bit now. Are there any other meds I should try? Can I ever add new fish to balance out their numbers? This is the 5th day of their maracyn II treatment.
Any assistance is greatly appreciated.
