Hi, Can anyone help please. I'm worried sick. My two weather loaches and two goldfish have Ich and I don't know the best course of action. I have raised the temperature but don't know whether to buy Protozin tomorrow to use, or I can use Tetra Medica Lifeguard tablets now as I have already bought these, or aquarium salt which I also have but what is safe with weather loaches? My poor goldfish is flashing and has developed red blood lines in her tail and the two loaches look as if they have been salted they are so covered in spots and this morning before we went out, everyone seemed fine. I cannot believe it can develop so quickly. I have got a 200 litre tank with a Fluval 206 external filter. The water conditions are ammonia 0, ph level 6.6, nitrate 10, nitrite 0 and I have two old weather loaches and two goldfish. Any advice would be much appreciated - I feel unable to think straight and being a Sunday night, no pet shops are open until 9 tomorrow morning. Will they be safe until then or should I medicate now?
