Hi y'all. I'm relatively new to the hobby but have graduated to a 40gallon breeder tank and I have some inverts, some corals, a dogface puffer, a fairy wrasse, and a singapore anglefish. Today after work I noticed the angel had one eye which is really opaque/ white and it wasnt like that yesterday. Worried it's something serious, from what I've read maybe flukes? Any reccommendations?
