Hey everyone, I know this is probably a dumb question, but i have a few baby Red bellies who are doing absolutely awesome in their tank and growing super quick. I notice (always at night and when the lights have usually been off in the room) that the ends of their fins turn black. Is this normal adaptation to nighttime environment?

Don't understand what you mean by there fins turning black,
can you give more information please.

I understand the coloration of the body changing during night time, but "fins"??? All I can come up with is that the darkness of the room might make the shades of the fins darker than usual. Other than that, I havent seen that in my Ps myself.

I have a Rhom that recently begining to show blue on his fins.. mostly the rear. The colors were showing a little bit when I first bought it from the previous owner, but now it shows even more, plus its in a tank with black backround
