Iso 30 gal corner tank (Petoskey)

Looking for a corner tank.
Preferrably not bigger then 50gal.
I have had to start all over during a move years ago and lost thousands of dollars in fish.
I used to breed several strains of guppies but Now I just want to start over with one display tank as therapy in my bedroom with most likely seal point angels.
My budget is tight but I can tell you as a seasoned fish keeper I'll take good care of anything that comes my way
