    I have slowly observed this fish loose its male coloration over the past 6 months. It is housed with a Vlamingi that is the boss of the tank.

    Any ideas on restoring his masculinity/coloration? It eats very well.

    Is the colour loss not possibly due to diet? Perhaps it needs more foods with the ingredient Astaxanthin?

    also, he has no one to show off too. imagine if no chicks were around, you wouldnt need to dress up. always get a female/male blue cheek, cos the male will keep his colours

    I heard that aswell - but i dont know the validity of it. I have a male for a few months and maybe i should look for a female now.

    Have also heard stories of males loosing colour if no female is present, thats why I got a pair from the get go.

    Interesting, if the fish is getting alot of fresh food with soaked in vitamins then, you can count malnutrition out as a cause of the fading colour that is the first thing i would check.
    Also if the fish is eating very well but shows lack of colour it could also have a large number of internal worms or other parasites and i would then soak it's food in a dewormer medication and perhaps after a course of metronidazole for any internal protozoan parasites.

    The theory of it reverting back to a female once a male im not to sure about that , it does have alot to do with dominance the sex change as most of the triggers in the harem are female and the most dominant female normally replaces the super male in charge of the harem. Keeping these triggers singly may also be a cause for the fading colour as the colours play a large role in their social interaction but id look at the first 2 causes before this.Females still have relatively pointy dorsal and anal fins not as rounded as in your pic.

    Thank you for the thoughts. I will give the deworm a try and add extra vit to the food and see if it helps.

    But i think i must find him a play mate as i will be moving him to a bigger tank in the next few weeks.

    @neil,h he is about 180mm

    He gets a mix of frozen Van Gerven foods, Krill, Artemia, mysis, choped muscles, lobster eggs, Stint and then also some Omega one pellets. He also pecks on the red and purple nori i feed the vlamingi.

    Will add immuvit to his food tonight.

    Had him about 10 months now. He was fine for about 3 months then very slowly started to change. He is big buddies with the vlamingi. They swim and play together.
