I currently have a dilemma with my female Percula Clownfish; she's gone blind. The fish was perfectly healthy while she (and her mate) were residing in my old 120gal reef system. When that system was torn down, the pair of clownfish were moved into a temporary system along with a couple pieces of live rock and two colonies of Duncan corals (hosting the clowns) and some various mushrooms. Over time, I noticed that the female clownfish would not venture far away from the duncan colonies; keeping constant contact with the corals. During feedings, she would dart a short distance to grab some food before going back into the corals. I could sense that her vision wasn't quite what is was as she would often miss grabbing some food. More recently, she won't ever leave the corals and I need to target feed her with a long pipette. Even now, she frantically bites at the food trying to catch anything that makes it into her mouth. It's quite sad, really. The temporary system is my old Fluval M60 with some live rock and ceramic beads for biological filtration and filter floss for mechanical filtration. The lighting is provided by the Ecoxotic Panoramic strips that I used to use on my frag section of the sump. The corals are doing okay; they open and look healthy but not as vibrant as when under the Radions and T5 bulbs. It's more or less a "furnished" quarantine set up. I have not ever experienced a fish going blind before, although Bill Capman had a similar experience with his male clownfish when it was moved into a new system. The fish is healthy, but it was just not behaving like itself and I noticed that the clownfish's vision was impaired. So this experience isn't unheard of. Has anyone else ever experienced a fish losing its vision from a transfer??? Or another reason??? I have been debating on moving the pair of clownfish into my office tank; for a couple of reasons. Foremost, I'd like to be able to take down the temporary system. Secondly, I wasn't planning on placing the clownfish pair into my new 120gal system. What I'm debating on is, will this additional move be beneficial or more detrimental to her health? In the temporary system, I can easily feed her and know of her location. In the office system, she could end up hiding/residing anywhere and it may be difficult feeding her. I'll most likely move her at some point; it's just when... and where.
