I was hesistant to agree that discus could be raised in a planted tank, but after looking at your tank I have completely changed my mind. You must have put in regular water changes needed to grow these guys out. Usually the planted tanks that I see all have stunted or emaciated discus, but yours has large round ones. I wish I could have tank as nice as yours. I'm looking at a bare bottom glass tank which is pretty boring to be honest. I sure miss having lush plants.
By the way, are those stendkers? I recognize the pigeon snakeskin and the blue snakes, but I don't know that they had red alenquers. Anyways, congrats on your success in the planted tank. You've proved me wrong.
