I recently had an unconfirmed columnaris outbreak in my 20G long.
I lost my fry and a few juveniles.
My adult male guppy is fine.
tested my water today 0 ammonia, 0 nitrate, and around 5ppm nitrite.
I double tested to make sure I hadn't screwed up, and 3 people confirmed color coding for the test tubes.
The other day I had 5 healthy looking guppies, and I'm down to 2 now.
I saw a ghost shrimp tackle a juvenile guppy, at about 3/4's of an inch from the filter intake, and thought nothing of it.
That is until I found it's skeleton on the floor of my aquarium later that day, picked clean.
I figured these were omnivores, but I didn't think that they'd take anything larger than fry down.
The shrimp are about the size of my adult male guppy- finnage about an inch.
I like them, but would rather move them then have them eating my guppies!
Has anyone else had these ghost/Glass shrimp eat juvenile or adult fish the size of a guppy?
