Blue rams- normal or not
Hi, I’m really new to this whole aquarium keeping. We have 6 rummy nose, 3 bristlenose and 2 blue rams (got the rams 5 days ago not sure of sex and noticed that one has no pelvic fins but seemed fine)... the 38L tank has been set up for 4 weeks now. One of our rams seems to have changed color, it’s still got its blue but it’s not as yellow on the head as the other, they both seem to be eating. I have read that fish change colour when something is wrong... Is this normal?
