Sick Purple Square Anthias

[Nemain]

I ahve had him for 8 months, he was one of the first fish I put in the tank. He eats my special mix of stuff, some from the grocery store ( shrimp, fish bits etc.), PE mysis, cyclopeze ( just a smithering), all saoked in slecon, then frozen into cubes.

he has never had a problem before this, hence why I am so worried. He isnt thin, he eats heartily, and has actually grown a fair amount in this time. His colouring is fantastic, even now. No paleness or dicolouration at all.

Latin name: Pseudanthias pleurotaenia

Thanx,
