My tanks at 80 f so it’s pretty warmI’ve had limited success with runny noses despite them being one of my favourite tetras. I buy a group of 10, 3 die, I buy a group of 6, 2 die etc. they do better in larger groups being tetras obviously , but I’ll admit to going off website temps of 25c ish. They do better in a slightly warmer , although you’ll not likely find that info on most sites.
I edited my above post , just so it doesn’t seem like I’m being strange hah.My tanks at 80 f so it’s pretty warm
I can check the ph in a little while I’m glad some others had troubles with there rummys too.I’ve acclimated them a ridiculously long time to a qt, kept them for 2 months happily in qt, then done the same acclimation to a same spec tank and have still lost fish. I know a lot of folk on here have the same issue’s with rummy’s , or they die within 48 hours of being brought home. I know you’re asking op , not me , but it does seem to be a recurring theme that’s either put down to either weak genetics or low temps, which op doesn’t seem to have.
more tank info would be ideal to help though , and 2 fish isn’t ideal for a social school. pH would be good to know as I asked before but full tank specs are more useful obv.
