all my water parameters are good 0 ammonia 0 nitrite in my 125, i once had a 9 inch jaguar cichlid who when i studied his gills they seemed to never move like he never had to work hard to breath even when he would swim rapidly, however i my little cichlids around 4 inches seem to always be breathing hard. is it just becasue they are small and have to work harder to breathe or is something wrong, the only thing that i think it could be is that im over priming during water changes, i use enough for 3 doses for a half water change, could this be the problem or is it just normal for small cichlids to do that? other than that theyre very healthy and are growing like weeds
