first of all ive never bred fish before so all the help available would be greatly appreciated. i currently have 2 tanks. one established and one just finsihed cycling about to be filled this week. i would like to start breeding and my lfs is happy to take any babies from me (not for a price, i just want to see them rehomed as i cant keep them all obviously). the new tank will have 1 male and 3 female black swordtails, 1 male and 1 female black mollies. from what i hear these will breed like rabbits so i wont have any problems there. my question is really about whether i would be best (as a beginner) to try to breed cories or bettas (or even none at all if you dont think i have the right tanks etc - i only want to breed if i can do it properly) as i wanted a bit of a challenge breeding egg layers rather tha livebearers.
here are my tanks:
10g established - 3 albino cories and 3 bronze and a male betta which i plan to move into my other tank shortly.
35g new - pictus catfish, upside down catfish, common plec, 2 black mollies and 4 black swordtails
im well aware that my plec will soon outgrow his tank however he and the other 2 catfish are rescued from somebody i know who threatened to flush all 3 of them if i didnt either take them or find somewhere for them to go. hes only 2" long at the moment so is fine just now anyway.
now, if i were to bred the cories they would just do so in their own species tank. if i were to breed bettas, i would keep my male betta in the tank with the cories and have 3 or 4 females in the larger tank and i could move one of them into the cory tank for them to breed then move her back.
i plan to rescue a small amount of molly/swordtail fry and have them grow up a little in the cory tank as no fry would be safe with the pictus.
any opinions/advice/criticism would be greatly appreciated - like i said i only want to breed if i can do it properly so i dont want to start without all the advice i can get
