Thank youWelcome!
Hi! Thank you. I did a big water change last week, I will clean his gravel and check levels. I Thought it was just his colouring or from the food.Hi and welcome to the forum
Does the fish have red lines in the fins?
If it does, check the water quality for ammonia and nitrite. And do a big water change and gravel clean the substrate every day for a couple of weeks.
Make sure any new water is free of chlorine/ chloramine before it's added to the tank.
