angels update 4

All the fish in the tank are eager for food, this morning. Nobody looks stressed. I checked water parameters twice since treatment ended- yesterday after doing the water change -37% because that's how much bucket space I had (the instructions recommended 25%). Ammonia and nitrite, zero. Nitrates 30-35 ppm.

The fishes are improved, but only partly. The golden sisters still have pale patches on their pectoral and tail fins, but much smaller, almost completely gone. The still have red streaks on edge of body below dorsal and on caudal peduncle, but it does look a bit less. Not sure if Precious has patches on the body, too- or was there a smudge on the glass

Shirley still has white on her lip. I think it's gotten smaller, but it's really hard to tell.

I got a good look at the kuhlis, which all came out to eat this morning. They're plump and active, but very red around the gills and pectoral fin area. I'm kinda surprised the biofilter doesn't seem to be affected- so guessing the kuhlis are irritated from the medication. Water is still kinda foamy, so going to do another wc today. Larger, if I can (my extra bucket is holding the substrate I was soaking, need to find another container for that). 

Trying to decide what to do. My options:

Just do extra wc daily, maybe with aquarium salt

Do another treatment round of Erythromycin 

Switch to Kanaplex, or maybe Fungus Guard (if I can find it)

Any of the above, but moving the two affected angels into the QT instead of treating the main tank again (which is going to start getting expensive here if I have to go buy more Erythromycin, etc)

On another note- in spite of not actually being planted yet, my aponogeton bolivianus is doing fine. Two of the smaller leaves melted, but the largest ones haven't, 

and it's sprouting new ones!

I'm going to put pothos on the back of the tank, again, to help take up nitrates. Took cuttings from one of my houseplants. Put them in a shallow tray of water so the roots will go down horiztonal from the stem (more or less).
