Yellow Tang Only Eating Purple Algae

[Ford101]

Hello everyone, I've had my yellow tang for about a year now and he seems very happy and healthy with good weight. I just set up a new 80gal mixed reef back in December that I transferred from my 3 year old 75 gal system. Everything seems healthy and normal except for his diet recently. I bought a pack of the Julian Sprung's purple algae about 6 weeks ago for my tang and he absolutely loves it! However he won't really eat anything else anymore since I started feeding that. He will eat about 1/2 sheet a day. He mostly avoids the other colors of algae now - before he loved green and red. He will still eat veggie pellets. I also feed rods food original 2x a day which he typically avoids as well- the rest of my fish love it though. I'm simply worried his diet is not varied enough, is there anything I can do to get him re interested in other algaes again? Like I said he seems happy and healthy but I just want him to stay that way and I know a varied diet is important for longevity and immune system health. Thanks for the help!!

maybe roll a few different kind of sheets together and stick it on the clip so he gets the others with the purple

Try rubberbanding the other kinds to a rock in the tank and see how he responds.

Both great ideas, I did mix the algaes together this morning, I'll see how he took to it when I get home from work. I'll also try affixing it to rubble rock as well. Thanks!

how long have you had this tang?

how long have you had this tang?

Almost 1.5 years, like I said he used to love the other varieties, but now won't give it the time of day unless it's that purple (which he goes nuts for).
