Sorry, my pictures are not at this computer, could not upload attachments. Here they are from photobucket:
Fish before moving to a hospital tank, same now:
Old photo, size comparison with adult chromis:
Frayed right fin, possibly bacteria on the bottom fin:
Yesterday they returned, fish feels bad. No ammonia.
Bulbous transparent growth on the right fin, no progress, no changes:
Edema (puffy) top of the eyes, disappeared after treatment, yesterday started to return back, in lesser degree:
Eyes are not cloudy, checked, this is reflection.
Tail, likely lymphocyctosis(?) that they have since beginning, Nov 08. Slight bacterial dark perimeter, slight fraying in one place. Translucent thing doesn't looks like parasyte. Fish was treated for parasites at arrival.
Hospital tank, 20g long. I don't have the larger one.
Angle of fish is either because of strong frow, 400 gph, or it feels safer seeing own reflection. Fish changes position in low low area to the normal.
Emperor 400 with established wheels from main tank, 1" thick foam inserts, also from the sump of established tank, in place of cartridges, small foam prefilter. Micron pads are before foam, not changed all the treatment - fish is not eating, they are fairly clean. One was replaced yesterday, after that all symptoms returned back, in hours. Fish is listless, tail down, what is unusual.
Daily testing ammonia by API test kit. Once after water change was slight rise (still below the lowest on scale), giving support by Seachem Stability.
Plant was added for moral support: fish is shy and easily spooked (each of 3 I ever own), familiar object pacified it.
First such fish died 2 years ago from the same symptoms, during first kanamycine doses, I couldn't keep hospital tank without ammonia them, but it was low. LR from the tank with this first fish was reused in a new tank, 1.5 yrs after first fish death.
Diagnosis and treatment were done by knowledgeable people at RC forums (lymphocyctosis for these fishes and kanamycin for the first filefish). One of them was keeping the same type of filefish for 8 yrs, it worked for her.
Other fish is unaffected at all, including different genus of filefish. The second pencilligerus filefish in the main tank has lymphocyctosis since beginning too, hint on a black perimete on the tail fin, but no white bacterial spots, has excellent appetite and very active.
