Albino cories still flashing
on occasion. By now the red is gone, all seems well.. ie recovered from (earlier post) blind cave nipping on them.... (ps any one who gets blind cave tetras, needs to know they will roter rooter soft leaved plants, and small fish, ie go into frenzied feeding habit like pirana and eat small holes in what ever, also out run even larger fish at feed time - great fish by themselves though.) I digress.
10 gallon with two filters, one from established tank, and box... one passed, one left with one eye ( hemorrhagic septicemia had set in) fins grew back, red bloody inside outside gone, and all seem a-ok..
Now, every once in awhile, esp at feeding time, one or two (may even be one with missig eye, they are hard to see they twitter about so fast).. flashes, dives so on, definately tries to scratch against bottom of tank. There is no sand is this 'hospital' tank. Tank has small piece driftwood - soaked prior to placing with salt so on, just in case, with java ferns plantlets. And some soft silk plants. For the most part they all look well.
One bronze cory had done this in another tank, but after I cleaned bottom - which I do twice weekly anyway, it stopped, this was awhile back.
I cleaned the fluvial to my water holding tank, where I have a chemical filter (stuff to remove chemicals) and a fluvial filter. Water comes from showerhead with filter. Midtown nyc water in my building comes out brown! It was pretty smelly! After one month - was suprised. So my water that I was putting in tank may not have been best???
(I clean bottom every other 3rd day or so (just part ie not alway vacume clean, thin layer of sand anyway as anubias are on wood on suction cups, just enough to exchange some water, and dribble slow fresh water) Part of this reason is the ph goes high and I think nyc has added lime to water system from research I did.
Regardless no other tanks have this flashing going on.
Stops for a few days, then back to that behavior. It is a definate type of scratching/flashing movement. I add fresh water, wee pinch of salt, and bit of stress coat.
I have no idea why/what is causing this. I assumed that after a month or so (since last post on original problem) what ever is causing it would manifest by now....get worse to be able to see what it is?
Amnonia, nitrates, nitrites all zero. (just tested again)
Right now, I took a peek - the hospital is on my desk next to my computer. As usual, with lights off, they are swimming around, on plant up down walls. No one flashing, but I don't look too long.
This darting/flashing behavior is not by all, only one maybe two.. they do all look alike, lol. and not constant. again, the cleaning off the bottom seems to stop it. I do partial water change normally twice a week along the idea of smaller more frequent changes.. in this ten gallon about 2 inches. I take it mostly from bottom. I feed lightly in am, and even lighter early evening.
Any ideas, thoughts help! High ph. 7.6???
Although, the one albino from earlier purchase and different lot in large 20 tank doesn't do this. Same ph. Same water source.
Residual bacteria from earlier episode of hemorrhagic septicemia...(what ever that means, as bacteria is everywhere, lol)
Ick, hard to tell on albinos, and I would think it would spread and get obvious by now.
Some sort of other micro parasite?
Or just strange behavior by this one or two cory?
Should I treat tank with what at 1/2 dose to be sure. Isolate the one guy and treat with what at 1/2 dose? Don't wish to use meds if don't have to but just when I think it is over, starts flashing again.. as if his gills are irritated...
Any help much appreciated. I would like to put them in the 20 long, which is long established, dark with wood and annubias. All to themselves. Would like to make sure they are disease free as it would be hard to capture them out of planted tank so on. Thanks Sherry
