I bought these very interesting looking purple/blue tetra’s (as listed on sale tank) today from lfs and I added it to the main tank in my bedroom. My daughter told me the angels & discus would eat them, I told her they should be ok. Their small, but not tiny small. I acclimated them, then let them lose & mama (black angel) was trying to eat them. The discus just do what they angels do & were chasing them too. They hid under the wood & in they fake plants. I decided to move them to my daughter’s 10 gallon tank with black tetra, mollies, Cory’s & my wandering bristlenose until they get a bigger. Anyone familiar with these tetras?
