My plan is :
#1
Put a pair (male & female) or 3 fish (one male & 2 females) of goldies i wanna breed in a breeding tank of their own with already cycled water, airstone, sponge filter & breeding mops/plants. females & the male are separated by a net or sumtin like that. feed them high-protein food for a week or two until the female is full of eggs, then gradually raise the temperature to induce spawning behaviour. once spawning behaviour is observed, lift the separator net to allow the goldies to mate.
OR
Feed high-protein food for a week or two in their original tank, wait till the females are full of eggs, then raise the temp gradually to induce spawning behaviour. once spawning behaviour is observed, move the desired male & female pairing into a ready breeding tank (cycled. aerated, sponge filter, with breeding mops/plants) and let them mate.
#2
Once the eggs are fertilized, get the parents out of the breeding tank into their original tank, leaving the eggs in the breeding tank. Put a dose of methylene blue into the breeding tank (which now has become a fry tank) to prevent fungus. Remove the unfertilized eggs as best as i can. Let the eggs hatch, wait for a few days until fries are free swimming, then feed them crushed pellets and egg yolk (maybe brine shrimp or daphnia if i can get my hands on them).
#3
Haven't thought about what to do next yet
PS : i wanna choose the breeding parents (e.g. ranchu with ranchu, fantail with fantail), not just some wild cross-spawning action
cheers & thx
