First the tank available is 72"x30x30 acrylic, is that footprint acceptable for any of the chichla? I know intermedia and kelberi aren't quite as big as the others so was crossing fingers on one of those.
Don't Flame for this next question and yes I understand the variables, only seeing if my schedule meets the needs. if there were 2 adults in that tank what would be the estimated bare minimum water change % and frequency to prevent nitrate build up? I already do more water changes then necessary and I test my water, the issue is my job will sometimes prevent me from maintaining an exact precise schedule. So I change my water every chance I get sometimes every 3-5 days once in a while it has to go 5-8 days but I always keep nitrates around 10ppm and rarely do they ever exceed 20ppm. I'm not asking for power growth and feeding, I'm just asking for purposes of keeping the fish healthy and not go to test water after 6 or 7 days and be OMG there's 80ppm nitrates and need multiple 50% changes... As far as I see it if going 5-8 days results in 50% changes daily to catch back up on water quality then these fish exceed what I could responsibly commit to.
