As someone who has owned Axies, the fact that you are keeping such a large ammonia machine like that Pleco with your Axies frankly horrifies me
Axies are so delicate, they need space in an aquarium on their own. They absorb everything that is in the water through their skin and a Pleco is such a messy animal, you would be doing two or three water changes a day and that Pleco will still poison those Axies
Axies are almost extinct in the wild...probably already are extinct. So we as humans must be considerate of their needs, their health and welfare at all times when we keep them in our home aquariums
Pleco's and Axies are nocturnal hunters......their diets are polar opposites, if the Pleco feels that the Axies are encroaching on his space he will attack...and Axies will retaliate. You will (not might) wake one morning to a scene of sheer carnage if you continue to keep those animals together...even on a temporary basis its absolutely wrong and cruel.
