As my Angels became very large they chased and ate the medium to large Neon tetras, of course the new younger small ones I added, (slurp). I found one with a tail sticking out of its mouth and it seemed a pretty big size Tetra. I believe they went after a couple when the Tetras were zoning out in groups.
This isn't really any answer to the question, other than I would make darn sure they were big sized and not smaller ones. Most ones I have seen lately have been similar to Neon Tetra sized at the lfs
. Could end up an expensive treat. My tetras had so many places to hide in a 72G and I lost about 25 before I realized what happened out of about of 100. Those Angels are adept at turning and sliding through the most narrow of spots. I watched one Angel charge a group and bite at a Neon, but my coming close to the tank startled the angel and it backed off /jumped a bit and missed the Neon.
New to FW fish? First tank in a long time or EVER??? Need some info on keeping fish?
