Dave Apistos are eager to spawn so just hang in there and things should happen on their own. As all south american riverine Cichlids love water changes are the best trigger to getthem to spawn. As you have noted water changes brings the level of dissolved waste down as noted by the reading on your TDS meter. Keep feeding heavy and doing regular water changes. bringing the pH up is not the best idea s their native water are rather low. I have spawned Aggies in very low pH myself with great results. The key to spawning them is lots of food and very clean water. Water changes will stimulate them to do what comes natural to them. One point to consider is trhe fact the Apistos are short lived fish so if you bought them very large it is possable they are past their prime. Older fish takelonger to spawn then younger fish and older fish take longer to acclimate to new tank conditions as well. I would only suspect age at as the last resort. Everyone has given great advice so just take the pieces that will help you the most Good luck Dave Sanchez --- email@example.com wrote: > I have a pair in a 15 gal tank by themselves and I > can't seem to find the trigger that will get them to > spawn. > > They both at times look like there is some interest > as the male on occasion will flare the fins and go > through some body posturing.
