I remember you lost a zebra & an altum. You shouldn't feel bad about them, your 046 was quite old even with your good care. Your 1 surviving altum, well, the rest of its original group had died.
I think you can cut back on at least some of your tank maintenance. Maybe not the pleco fry grow out tanks as much adult fish tanks. I admit I have lightly stocked heavily planted tanks & do both smaller & less frequent WCs sometimes. Your clown loach tank probably has the most "fish mass" & might need more than say your plant tanks. Now, your altum tank has only 4? plus some other fish probably but fairly lightly stocked I think. It's a larger tank with plants & water that needs extra prep...hmm, I might cut back on that 1. You have TDS meters...use them to help decide WC needs, a little raise in "usual" nitrate level isn't a great big deal & TDS meters are a fast way to check. Go slowly on cutting back & judge by fish behavior too.
The adult pleco breeders...maybe they'll breed a bit less with fewer WCs, not a terrible thing. Or (egad!!) start pulling the females & put them with their same species fry? I know that's a difficult option but you'd still have proven breeders to make up "sale breeder groups" & no new fry...Otherwise you'll always have more eggs & fry...just when you want out of this wonderful breeding pleco madness. I don't see another way for you to stop this year...or 2?...
