Hello to all, i am new here and also new at apisto breeding.i am planning to breed apistogramma agassizii or cacutoides.i have done extensive research and my only problems are tank space and very hard water.So firstly,i know 20 Gal is better but can i breed my apisto pair in a 10GAL if i can grow the fry in another tank?(how big should my fry grow out tank be?) and if yes what should i keep in mind that may be troublesome? secondly,what worries me is my GH (my Kh is 8) which is high at the moment.GH is 14 but i am pretty sure that's because i keep topping off water(which is already hard) the last weeks instead of doing water changes(cause im medicating) and all the mineral build up goes back in the water and adds up.So i dont think my GH will be 14 but it is high anyhow.How much i need to drop my GH for my apistos to breed and eggs to hatch? from what i know, hard water can mees with eggs hatching.is there some merch that i can use to make my water softer? I need your Apistoexperience .Thank you!
