No, the nitrates were hitting 20ppm in the 75. That's why I upgraded. Because my goal is to have maximum health for my fish. Not to shove as many fish into a tank as I can and hope they make it. African brown knives do reach a foot, but the typical mature specimen (from what I understand, I haven't kept them) is more like 10". That's still 90" worth of skinny fish to reckon. Of course, in your tank with its accumulated metabolic byproducts, they probably won't get as big as they should.one oscar in a 125 with a few raphaels? well thats very genrous. that could be done in a 75g.
You do a lot of water changes and that is great. Just how much does it take to keep the nitrates below 20ppm, each week? No bait in this question, just wondering.
Overstocking was never a good idea. If all your friends jumped off a cliff, would you do it, too?
Adding Exodons would be an unethical way to thin out your stock. It could take many agonizing minutes for them to rip the jag up...but in the end a tank with a small school of exodons has a much better long-term prognosis than your current ward.
