I've kept fish on and off nearly all my life.
Have not kept saltwater ( I think its unsustainable)
Right now I have devoted my 150gal.heavily planted Amazon tank to a school of 9 almost mature altum angels that are doing fine (knock on wood).
Sharing the tank are a small group of Buenos Aires tetras,pygmy and panda Corydoras.
Its my favorite set-up so far,and I hope to breed the angels in the future.
