Typical for a pigeon blood strain...the fish in question does look a little stressed, but the fins are nothing to worry about

[tboss]

They both act sick. Staying off to themselves and hiding. Not swimming much at all and now not eating.

[danotaylor]

Sorry, I missed the not swimming not eating comment. The black fins are nothing to worry about, the other symptoms are early signs of hexetemia. Order pure metro online, raise tank temp to 90-92, when metro arrives dose 500mg/10gal daily for 10-12 days, wc 50% daily before dosing.

That's where I get mine and I agree it's what is needed. If you can change more that 50% daily with stable water do so. The fish will be shedding the parasite in the water which reduces the quality of the water. It's like out with the bad and in with the good. You'll be able to fix this problem.

[tboss]

Okay, I have the metro on order. Is there anything I should do besides water changes before it gets here? Aquarium salt?

[LizStreithorst]

Raise the temp. Hex can't live at high temps. We recomend 90 to 92 if your heaters will get your tank that high.

[tboss]

Thanks. I got it up to 91.6 so far.

[LizStreithorst]

Good. If there is enough air getting in the water from surface agitation you will be surprised that the high heat doesn't bother the fish one bit.

[danotaylor]

A little salt (2-3tbsp/10gal) won't hurt, may sooth them a little, but it won't treat hex as it's internal. Liz is right, the oxygen carrying capacity of water drops as the water temp rises. If you don't have good surface agitation, add an air stone during the heat/metro treatment :thumbsup:
