A question for you all, about a month ago I bought 7 Paleatus Corydoras for my heavily planted 20 gallon aquarium. One turned a bit pale during acclimation from stress. It survived, and is doing fine, but has yet to regain hardly any of its coloration, with just a hint of spotting being visible. It eats well just like the other corydoras, which are normally colored. Why would this be? Thanks in advance!
