OK well for starters i have a 10 gallon tank with 5 neon tetras, 1 black tetra, 1 betta, 3 white clouds, 1 pleco, and fake silk plants. I also have a 29 gallon tank with 7 zebra danios and 6 diamond tetras with live plants. Anyway i would love to breed angels some where in the near the future. So i was considering getting a 20 to 25 gallon tank for the angels alone and no other fish. I was thinking java fern for the plants and a few decorations. So the angels would breed and once the fry develope for a few days and become free swimmers i hope to move them away from the parents and into a small tank. Something under 10 gallons. What would you recomend for the size of the tank and all of the supplies i need?
