So I brought home some guppies and ghost shrimp from my lfs and didn't quarantine them because all of my tanks were occupied. Three females and one male. Seven ghost shrimp. The stocking before them was
6 rummynose tetras, 4 neon tetras, 5 five month old mollies, 2 oto catfish, 7 adult guppies and one guppy fry.
Two days afterwards I notice that a two of the new guys didn't look so good, swimming slow, flat fin, and hiding a lot. Next day those ones are dead and the rest of the new ones and one of my old ones sick.... this continues until about 2.5 weeks later all of my adult guppies and two of my mollies have died. My tetras, catfish and shrimp are healthy as can be. What do you think ot could be?
Temp is 78-79f
Ph is 7.0
Ammonia 0.25 (it's a little high but I'm doing large frequent water changes and it wont go down)
Nitrate 30ppm
Nitrite 0ppm
