Black Moor sick?!

[mjw]

HELLO! I’ve had a black moor in a 55L tank for about a month now and got him when he was little but recently he’s been sitting at the bottom of the tank, he’s also developed some white on his fins and I believe it’s fin rot? Have ordered some medicine and is coming tomorrow (THANK GOD PRIME EXISTS) is there anything else I can do to speed up his recovery? Or maybe there could be something I’m missing? Thanks :)
