Hi everyone Oi oi oi...last weekend I added rummy noses to my 180L planted tank without quarantining Two of the 10 were already floating in the bag by the time I got home (20 mins drive). Another 2 didn’t look good even during the drip acclimatisation and I kept them aside (they died shortly after). The 6 released into the tank looked fine initially but towards the evening/ next day i saw some white spots on them that I hoped was ‘stress ich’ but started dosing the tank with Microbe-lift Herbtana. 3 more rummies died over the next day or two. The remaining rummies look fine and they hardly have spots left but this morning I noticed some on the other tank inhabitants. Just a few small spots but still. PH 6,5 (normal for this tank), Ammonia and NO2 0, NO3 around 15. No other losses in the last 2 months. Other inhabitants: otos, sterbai cories, khuli loach, platys, diamond tetra, danios, SAE, shrimp and snails. Today I bought (but haven’t yet used) Quick Ich-X. I also have Paraguard at hand (haven’t used it). I have been keeping an eye on similar threads, and it seems as if the salt (normal table salt) and heat treatment comes recommended as a first line of defense by @MariaS ? Would it be safe for my other inhabitants, and what temp and salt dosage do you recommend?
