Cherry shrimp getting picked off?

[DarkDH]

2 days ago I introduced a group of 20 cherry shrimp into my 20 gallon planted aquarium. Yesterday ( a day after they came from shipping) I did a head count, and all 20 were still alive. When I went to look at my aquarium today, I noticed that I only could find 4 remaining.

They were grazing on biofilm yesterday and had started to get their color back. I have a sponge over my filter and plenty of mosses for them to graze/hide in, yet I can't find the rest.

My tank is a 20 gallon long, with 0 Ammonia, 7.4 pH, 0 nitrite, no copper, and planted. Tank mates as MTS, Upside down catfish, cardinal tetras, and ramshorns.

They may be hiding, Mine were amazing at hiding in my planted tank.

My other suspect on a down note would be your Upside Down Cat snaking on them.

My bet is that my trio of Upside Down Catfish are taking them out. There went my $20 investment...

I am sure the upside down cats loved your fancy expensive feast for them. LOL Sorry, maybe you will get lucky and they are just hiding.

Yeah most fish will consider any shrimp tiny enough to fit into their mouth, a snack.

what are the other fish in the tank?

Cardinal Tetras, Upside Down catfishes, and MTS.

Well, I did another head count, looks like I have 6! 1 adult and 2 juvies. Hopefully they can breed the next generation...

I have plenty of mosses and places for the shrimps to hide, so if they do breed, hopefully I'll get at least 4 or 5 new shrimp.

Yeah, I say the upside down catfish is getting them.
But, they are also extremeley good at hiding, so you may have more shrimp than you think.

Upside down catfish probably
