Tried to introduced 10 of 30 Cherry Barbs to my established 90 gallon community tank with 2 large angelfish, 20 black neons, 15 X-ray tetras, 10 peppered Cory Cats, and several BN plecos...
My thought was with 10 they would school together and hold their own.
What really happened was there weren’t enough of them and they scattered as soon as they hit the tank... I can only assume since I feed a lot of red food (Xterme Krill and Hikari Vibra Bites) and their size the Angels started going after them one at a time and even the larger tetras did as well...
The lesson is to only introduce bigger community fish and in larger schools as the Angels and the Tank are so big...
