I have had serious Mantis problems. I lost several nice fish. I have caught two so far but I still have a big one in there that makes a lot of noise. Get a clear water bottle 20 oz. or a 2 liter coke bottle. Cut into two pieces about a third of the way from the top or a little less. Remove...
I have an Orange Shoulder Tang, He is bright yellow with the distinct orange shoulder and a small dark spot on the tail. He looks much different than the one on your page. Is this a juvenile stage, different --- or a slightly different species?
I had a 29 h with a tomato, a percular and a 5 inch very aggressive huma huma, they all got along fine for years, but the trigger would have been happier with more room and he was always well fed.
Dude,
They call them anchor worms, they are common on firefish, especially purple ones. Its probably bugging you more than it is him, but if it is in his gills it could eventually kill him. You can treat him a variety of different ways. You can net him and physically remove it with tweesers...
