So I have 2 4-4.5 inch discus that just got out of quarantine and today I put them in my display tank. Before I got those 2 discus however I originally had bought 2 discus from a LFS, one of them however didn’t make it. When I put the two new discus in with my one original discus I could definitely tell there was a size difference. Ever since I’ve bought that one discus from the LFS it hasn’t grow which makes me think it’s stunted, it’s at most 3 inches. I plan on getting 3 new discus soon to make sure there is a large enough group for them to thrive but I’m wondering if having the one discus 1-2 inches smaller then the rest could be a potential problem. Pretty much the whole day the original discus has been hiding from the others. Should I maybe give it away since it may not do so well?
Thanks Lucas
