I have cut back on water changes on my 4ft tank ( 1 gallon per week) the stocking level is 8 halequin rasbora, 10 ember tetra, 8 cory's and a bucket load of cherry shrimp.
I have noticed an exceptionally hi amount of sporning activity in all the species with a major load of eggs from the 1 Cory ( all females 😢) would I be wrong in assuming the eco system is more or less in a happy equilibrium that being said oh is sitting at 7,4
