I have a pair of Killifish Gardneri that I wouldnt mind breeding. Right now they are in a 10gal w/ two kribensis....Over Stocked right there but dont start with me on that...but the question I was going to ask was I have a 10 gal that I have heavily planted with only a betta in now to keep it cycled and some shrimp. The problem that I have right now is how much difference will the hardness between one tank to another affect the fish...the krib tank is about an 8 dGh and the other is about a 3 dGh...and if so how would be the best way to change these fish over....also the pH is about a point differnt...7.4 to 6.6...would the drip method be the best for acclimating them prior to putting them in there? Anything else I should know?... Also about breeding them...how good of parents are they and will I need to move the eggs to grow them out, etc.
