ypu i think it is bicolor. Jireh lady boss say it is an algae blenny when i want to buy a algge blenny. Anyway it does eat algae, can see a lot of semi month mark on tank glass after intro.
yup stock too fast. Did not qurantine fish really regret (YT got fungus growing on fin). Now stop buying fish and have set up a 1 feet qurantine tank. Try to catch YT but failed. Who got fish trap to T-loan?
