Just brought this guy home yesterday, and when he finally came out in light today eating, I noticed markings that on closer inspection may or may not be skin markings but instead some kind of white skin growth. Reading various sites has left me more confused than informed, so am hoping a closeup may allow someone knowledgeable to tell me if I have a problem? And if I've introduced a problem into my community tank? I have no quarantine tank but am perfectly willing to remove the one fish if that saves trouble in the tank. This is a relatively new setup, and while not a lot invested in stock, I'd rather lose one than risk all (unless it's too late -- he's been in about 14 hours). The image is quite high resolution, but the system here won't let me post it that way and show reduced, so I've posted a low res image you can see above, but if you use the link below the full image is available. That's about 10 megabytes so if you have a slow connection be patient. In some browsers it opens smaller but a click zooms. Tank details: 45G planted (lightly), cycled as of about 2 weeks ago, 78F, ph 7.8, ammonio and nitrites zero, nitrates about 10 (a bit under), KH6.5, GH 11, Fluval 306 filter, water clear. Substrate gravel + ecco complete. Lit 2 x 4 hrs with Current LED+. Stock: Adult striped raphael catfish, 5 x serpae tetra, 2 x congo tetra, 2 x small koi angelfish, a few snails and about 10 ghost shrimp. All happy and healthy. Plants: Jungle val, crypt wendtii, anubis, amazon sword (1).
