Hi! I recently acquired an aquarium on craigslist. 75G 37 inches wide, low-tech planted with some anubias. He had 6 angels, 1 Albino Pleco, and 2 SAEs in it already. I'd love to add a school of tetras- probably congos since they are on the bigger size. I know 6 Angels is already a lot, if it were me I'd only have 3 or so in there, and I could do without the Pleco/SAEs. I kind of want to rehome a couple of the Angels but I would feel bad, the original owner seemed attached to them. Whatcha think? Thanks for any advice, it's been a while since I've been in the hobby.
