Daryl......my experience was to put just the one pair in a WELL planted 15 gallon tank and fed the bejesus' out of them with live food. But remember I am a big believer that WILD fish are looking for a place to spawn, but not if it's not in there "natural" water conditions. You take a fish from soft water near pH of 4.5 and put them in my tap water and they will survive but the female will not come into season....there is NO proof of this it is just 30+ years of watching and listening to stories of spawning fish. The closer the fish are to wild the more the female needs the parameters of the wild to bring HER into "season" which in turn brings the male to readyness. If those A. gibbeceps are even F1 or F2 they need LOW pH and softness........mine spawned in pH of 4.8-5.1 and 20 microsiemens.....that's pretty soft, those are pretty drastic numbers! Certianly some of our valued tropicals will violate all of what I just said but those "difficulte" to spawn fish.......nature never made such a thing....difficult to spawn......they just need certiaN "THINGS" TO SET THEM OFF........give them that and i guarantee they will spawn. We did learn from the discus didn't we? In the middle 60's anyone who spawned discus was next to God........now that we found that all they were doing was giving them 83-84 degrees of temp and soft acid waters.....bingo.....your little sister could breed them.....just find out what sets em' off!!! Have a good day and have fun! .......Lisa, Santa will get you for this....HEH,HEH,HEH!.....just kidding!( that's inside folks!)
