This is Oracle, my halfmoon Betta. When I first rescued this little guy he was a beautiful white. I've been reading around the internet and have seen that many people's white betta have eventually changed colors once they got into a good environment. Does this look like the case? It seems he's taking on an orange/copper/red tinge to his fins and head along with some newly arisen grey mottling on his body and dorsal fin. He does NOT have velvet! When I mention "coppery" some people have jumped to this conclusion about the color but he is highly active and happy! Also, I have not fed a color enhancing food.
I'd say it's been about a good 3 months since I got my little baby and he's been in a nice tank with heater and gentle filtration.
Thanks for any input or similar findings! I generally lean towards black betta's, but Oracle was just so striking at the time that I had to rescue him from that TERRIBLE excuse for a fish shop!
