Why ? Any issue ? I have 5 spotted SD, all sudden with red

I agree with L3CTR0N perfectly normal. That is also an indicator that the aquarium conditions are good.

I noticed that the male Maculatus / Spotted SD, pictured center, is also sporting black edging. That is it's mating coloration.

But that tank all 5 spotted SD are also male, can they mate with the normal SD?

I don't know if the different varieties will spawn, but something sure got the attention of one of the males. Lol.
This is a pic of one I kept displaying his mating colors.
