Hi all,
3 days ago I purchased 8 new rummynose tetras and 8 new hengeli rasboras to add to my tropical community tank. I've added them to my 20L / 5 gal quarantine tank for 2 weeks before introducing them to the 200L / 50 gal community tank. The quarantine tank has been cycling for about 3 weeks with filter media from my community tank before adding the new fish, so it appears to be fully established. I also have added around 10 red cherry shrimp to the quarantine tank to help cleanup food while they're in quarantine.
Overnight, 3 of the rummynose have died suddenly. Yesterday evening, I saw one of them swimming erratically - rotating upside down, lying on the bottom, not being able to swim upright properly. I tried giving it a 15m soak in an epsom salt bath in case it was a swim bladder/constipation issue before adding him back into quarantine. When I looked at the quarantine tank this morning, I saw 3 rummynose already dead. No other obvious signs of disease other than that 1 that was swimming strangely. None of the rasboras are showing any signs of illness. For now, none of the other rummynose are also showing any signs of illness. Alll the fish look to be shy but have been eating flakes and pellets.
Water parameters are 24C / 75F, 0 Ammonia, 0 Nitrites, 5-10 Nitrates, ~7.8pH. I know the pH is a little high but the water in my area is a bit hard and I've been using the same water in my community tank for 2 years with other tetras.
I've added some melafix/primafix to quarantine and will probably do a 50% water change today but is there anything else I can try or lookout for? Maybe adding some aquarium salt to quarantine? I didn't originally want to add any salt as I wanted the quarantine tank conditions to match the community tank as much as possible and there's no salt in the community tank.
