I'm a fairly new Aquarist. But, I've found the breeding cycle and the rapid breeding nature of fish interesting. with my favorite live bearer being the sword tail which i currently have 4. I am planning a breeding/fish tank rack with 2 3o gallons or 33 gallon longs, 2 20 gallon longs and possibly a 40 long or breeder on the bottom and would like to experiment with breeding sword-tails. Just want some suggestions or advice on the subject i'm interested in breeding with black swordtails or koi swordtails and if i can get my hands on them the lyre/top fin variety. since it may be helpfull i can easily obtain koi,black,and mixed from a chain near me and i think possibly red's from my only local fish store. Thank you Nick.
