I don’t think they’re that young. They are well above .5”. But I’ll try to call them good call.jake37 said:So these are new fishes ? How long have you had them also I would ask the store if they have had any deaths if these are less than a week old.

I really can't imagine it being ammonia burn since you grew enough bacteria to handle 3ppm ammonia. I agree this number of little fish would not have produced that much ammonia 'specially in such a short period of time.Rcslade124 said:Yea that's mu thoughts. I just worry they looked pretty red that it might be ammonia burns. The rest this morning seemed fine. Nice blue and red. As long as none pass away while I'm at work I'll chalk it to a few weaker ones. If not I'm in trouble have 3 more fish coming in the am. Thinking about getting some safestart plus just in case it was ammonia. But cycled to 3ppm I don't think 17 juvie cardinal will cause an ammonia spike.
I have seen this posted from time to time but personally I've never experienced it and have been using Prime for about 4 years in all of my tanks.jake37 said:Be aware that since you used prime you will likely get a 25ppm false reading for ammonia. I find it takes 2 to 4 days for the prime to drain off before the false reading will go away. It has to do with how prime binds with ammonia (the fishes are always producing ammonia).

You could be right. It could have something to do with how strong the cycle is. I kept reading this so actually tried to recreate it in my established tanks and never got an ammonia reading.jake37 said:I think it has to do with the age of the tank. I just went through this with two new tanks. 0ppm ammonia; added some prime and retest a few hours later and it jumped to 25ppm. Since this was repeatable for 2 different tanks I figured it was genuine but perhaps it was real ammonia as the tanks were new (well the tanks were new but the sponge filters were months old taken from mature tanks - I start my tanks by taking mature sponge filters and 2 or 3 guppies - I seem to always have more guppies than I know what to do with... anyone want a guppy ?)
But the survivors look quite healthy !FinalFins said:Sorry for the loss. Yes, agreed with mattgirl , the fish may have just been weak. I also lost 4 fish out of my new group of fish also.
