I'm just wondering if anyone can help me with an issue I'm having with one of my males. I currently have two separate breeding pairs, one in a 20 long and one in a 29 high, both in planted tanks (the 20 isn't super heavily planted, waiting on some things to grow a little better until I plant some more). But the issue is that my male in the 20 isn't showing colour. He generally looks pretty pale, he usually has the stripe but there is never any stress signs. Hes been in the tank since January and when we first got him he was very bright including a very dark red chin. Ill upload a picture of him compared to my other male when I have the chance.
