Hello,
I have a 55-gal tank with a large green severum and an albino oscar. Yes, I know, too much fish in too small a tank, but it was one of those situations that we need to deal with for a while.
The fish have been healthy with very regular water changes until recently, when my Dad passed away and I had to be out of town several weeks. I didn't want to have the guy who feeds the cats do anything with them; I figured he would do more harm than good.
I came back (2 weeks ago) to high ammonia levels, nasty looking algae bloom in the water, and unhappy fish (they wasted no time telling me!)
Since then I've stepped up tank maintenance, doing water changes every 2-3 days. Until today it seemed to be helping, tho the water remains cloudy with this grayish-green algae stuff.
This morning the oscar went flippy. I didn't bother testing anything, I just started doing a water change. She's real sensitive to anything spiking too high. As I was cleaning things out, I noticed that there is slime in the tank. Long ropes of what looks like (excuse the expression) slimy snot, floating in the water.
I completed the water change and suctioned/netted all the slime I could get. I added aquarium salt and start-right and a new filter. Now the water looks great, but the oscar is obviously stressed - and the severum has what appears to be bubbles or tiny tiny crystals on his head. Almost like salt crystals, and just about that size, except these look hollow. Whatever they are, they are white and shiny, and are in a patch along the top of his head and toward his top fin.
I've never seen anything quite like it. We had another fish with ich, a long time ago - this looks nothing like it. Ich looks... ichy. This looks like someone wanted fish for dinner and salted him first.
Can anyone help?
