I don't do water changes often, maybe once every few weeks. I just did one about two weeks ago. There is a nice pot in the tank to spawn, and the tank is oh, 3 gallons. It has lighting and an undergravel filter, with a couple plastic plants and a pinch of live plants. The temperature of the tank is room temperature <no heater>. I haven't tested water hardness.. but the water I use is city water, if that helps :P I treat it with the ammonia, chloramine and hard mineral remover stuff, ph down <i have very basic water>, and ph stabilizer. :) thanks, Sue >Sue, > >Spawning fish has a lot of other factors besides just having a pair of >fish.
