I would say the lemon tetras would be best. Slightly higher body will make it harder for an angel to eat. And as for starting out with 10 angels, it would be fine to start out with and eventually re-home the females and extra males till you have only 4-5 angels left in the end.One of the tetra types should be okay
Not sure on that, never had either specie. I'm certain someone will chime in with their own experience.so 5 angels 4 keyholes, introducing them at different the keyholes at different times won't cause problems right? and then 10 lemon tetras will be the first in the tank. The tank will be at 78-79 degrees. Have a tetra whisper 40I and two sponge filters that are rated for 90 gals each. Also will be feeding freeze-dried blackworm, tetra flakes, and Hikari bio gold.
Also, are keyhole cichlids hard to keep? Are harder to keep that biotodoma Cupido, the cupid cichlid, or the same?
Driftwood would be good, but they could also like some plants and pots to hide in too.Okay that sounds good. Would driftwood branches be enough cover or should I add more plants and terracotta pots?
