Hello Sylvia Oh my god, you used Chocolate Gouramis as dither fish?? I can't get any of them buggers up here and you're killing yours off to get your apistos to spawn!! Just goes to show what we'll do for our fish. As to dithers, I never use anything else in my breeding tanks except the pair or the group ( some times i use trios or quads depending on the tank size) I used to keep some killies in with my pairs but that wasnt a good idea, had some casualities in the killies or severly tattered killies. My suggestion would be to add lots of hiding spaces, i e 5 or 6 flower pots per tank to keep the non aggressive one from getting beaten up too bad. Hiding places are great. I also use one flower pot that can be easily guarded by just one fish with out the other being able to get in if the female dont want the male in there harasssing fry or eating eggs. If you arent using bare bottom breeder tanks, lots of plants are good cover too. I now use some plants in flower pots in my breeder tanks. I still have a bare bottom but plants help ease some stress in certain species. I do this in almost all my breeder tanks. So I would recommend just the pair of fish and lots of hiding places, no dithers!! Watching your fish helps too, find out whos the aggressive fish and when its happening, sometimes removing a male after spawning is necessary for his or her health!
