I took a look at the pictures and treat with antibiotics immediately. Those fish have a severe case of hemorrhagic septicemia as well as ich. You will mostly likely lose a few of them at this point. They are also severely malnourished, showing signs of stunting, and probably burned by ammonia from the dead algae eater.
It's actually amazing that they are still alive. Do your best but don't get your hopes up to high. Even if they survive the immediate ailments the internal damage could lead to deadly organ failure in the coming months.
Really wish I had a better cam workin' (went out for meds and a new battery...gotta order online, can't win), but from what I've been told, read and seen I think you are correct. I have Pimafix, Melafix, and Maracyn - 2 and Paraguard.
The Paraguard has Malachite green in it (like the Quick Cure), the Pimafix & Melafix are supposedly botanicals that have Pimenta Racemosa & Melaleuca in them as active ingredients respectively.
The Maracyn-2 is the only one that mentions
gram negative or
septicemia by name. I only mention all of this because I really don't have a very good feel for what to do.
The water quality has been near perfect since day one and I've been trying to keep their feed as varied and hi quality as possible. Temps are now at 75f with a half teaspoon of salt per ea. 5 gallons and daily 50% water changes.
Which med do I use first on the really sick ones? I already gave the recovering guys a dose of the Pimafix and fed evryone the lo-carb slow sink pellets which they tore up.
Will feeding small amounts twice or thrice daily do any harm?
What is best food for them now? I have Gold fish flake & lo-carb pellets, tropical flake and lo-carb pellets, floating pellets, veggie flakes and wafers, brine shrimp flake, spiro, sinking cat pellets w/ brine shrimp, sinking pleco pellets, some generic tetra tropical flake, Koi pond pellets and flake and some garlic enhancer.
Should the tank have any salt at all and if so how much? It sounded good but with all of their other issues and needs I wasn't sure about the synergy?
Should I just switch them from tank to tank instead of doing the vac/water changes (which I'm sure freaks them out). I have no substrate in the other two available tanks.
Cold, cool, warm, tropical...I'm good at following directions (been married forever since the military), what temp is best for the really sick ones? The other two big fantails are recovering so far, their four smaller tank mates are the ones that look like death...but they keep hangin' on while I stumble through this.
Stupid fish...why can't they just tell me what the heck's wrong? You see, this is exactly why I stopped keepin' kids, well that and Social Services gettin' pissed about 'em bein in too small of a tank...:lipssealedsmilie:
