HerCrenVie;1245455; said:I'll definitely feed less from now on. No wonder my pike is the only one breathing heavily. It's so contradictory - you said heat is the key, but increasing the temperature will certainly lower oxygen levels, and you also said the water should be as well aerated as possible. As for the medication part, yes, I started treating the tank with Flavine/Acriflavine this afternoon. I'm using this and not methylene blue or malachite green because it is said to be harmless to beneficial bacteria, and the brand is pretty decent. However, the bottle itself also calls Flavine "a mild bacticide and fungicide". It certainly does seem mild to me, considering I followed the dosage (in fact I over-dosed slightly) and yet there hasn't been any visible improvement in the pike's condition. Do you think I should use a stronger chemical? I don't want to ruin the nitrogen cycle in my tank though.
Acriflavine has some anti-parasitic qualities, but I don't think its use is the one indicated here. If you are certain you are dealing with ich, a better choice would be a medication consisting of malachite green & formalin, which together have "synergistic" action - meaning their efficacy is improved when used together. Yes, the heat/dissolved oxygen quandary seems contradictory, but there are many ways to increase the DO (dissolved oxygen) but only one way to increase heat. Heat is the key to speeding up the life cycle of ich, giving it less time to feed on the host, less time to create more "babies", and giving those babies less time to find a new host. AND it helps stimulate the fish's immune system. DO can be raised a lot of ways, many of which have already been mentioned in this thread. I would strongly recommend you invest in an air pump, even a cheap one. It is worth the few bucks.
What chemical to use? I don't know what is available to you in Singapore, but my favorites would be Kordon's Rid-Ich, or Aquarium Products' Quick Cure. Neither are expensive, do not damage the biological filter when used properly, and easy on all but the most stressed and degraded fish. Look for something with a malachite green & formalin ingredient list. Again, be critically aware that such medications can be absorbed and broken down by organic debris AND REMOVE OXYGEN AS THEY ARE BROKEN DOWN. To avoid this, thoroughly vaccuum your tank every day before re-dosing. Doing such will also help the meds stay in solution (in your tank) longer, killing more free-swimming parasites. In short: get an air pump, heat the tank, use proper meds, and do lots of water changes. And then buy a quarantine tank for next time.
PROPS TO ANDRE!! WOOT! LoL! Don't forget to remove the carbon though, if you have any, or all this will be pointless!! OY!
(or at least was, just like the best of Norway, Slovakia, Denmark etc.).
