Let me first say that I've searched this site and others and can't find any definitive answers. I've not seen any posts where the person came back and said if the fish ended up ok. Last night I noticed lumps on 2 of my dojo loaches. I haven't done anything different lately and my water parameters were good when I checked before my normal weekly pwc last Saturday. Unfortunately, I can't test the nitrates or nitrates as it was the last of the testing solutions that my brother had given me. Can't get more until payday. Anyway, I'm going to do a pwc today and probably everyday while this is going on. I've got some melafix and jungle antibacterial food, but I don't want to medicate unnecessarily. Should I go ahead and try one or give the extra pwc a chance to work first? Sorry about this being long, I feel like all my posts are long winded. I'm really worried. Lowie was my first loach and I've had him over a year now. Nero is one of my medium guys that I've had for about 5 months. They're both still acting and eating normal. Please help! I'd be devastated if I lost either of these guys.
