I recently bought a 5 gal. Fluval Chi that was overstocked. I gave the fish to my friend and moved my HMPK from my son's 5 gallon into the new Chi. He seemed to be doing great but tonight (about 1 week later) I caught him flashing. I have a 29 and 45 being treated for velvet with Crypto-pro right now (those fish are finally looking better) but I'm worried I may have cross contaminated my new tank somehow. I don't see any gold dust on my betta (checked his gills with a flash light) but there may be a black spot. I can't tell if it's his beard or not because this feisty boy does not hold still long. He still has a great appetite too. Should I purchase more crypto-pro and dose his tank to be safe or is there another effective product out there that doesn't cost as much? I thought of Maracide but haven't heard much about it. I tried copper in my other tanks and it didn't do anything. That's why I'm now using crypto-pro. Any help or advise is welcome.

I am sorry for my lack of knowledge. But what is flashing?

Quickly rubbing against substrate and decor.

Sounds like a parasite problem.

For Velvet disease I use an ich cure medication in addition to putting about 8 copper pennies per gallon. Use pennies minted before 1983. Pennies minted after that date are copper coated zinc. Use the ich medication as directed and take the pennies out after 10 days. Also use half dose ich cure when treating fry.

My dad and mother in law stole all my copper pennies LoL! Will an ich treatment still work if it's worms or velvet? I'm certain it's some type of parasite.

So sorry, since you have/had a case of velvet in other tanks I would follow your gut reaction and treat him with what has been effective.

Out of curiosity.. how would copper help?
Thought that sounds pretty interesting c:

[Chard56]

A lot of parasite or ich medications have copper in them. You turn up the heat in the aquarium to 82 to 84 degrees to make the ich or velvet cysts release the larvae which then live in the gravel to reinfest other fish. The copper kills the larvae once they are off the host fish before they can re-infest others. A lot of people quit medicating once they can no longer see the white spots of ich or the gold dust of velvet but since the larvae are still alive they start the cycle all over again. You can't treat either disease until the cysts are off. Then you kill the larvae.

Copper didnt work on the velvet in my other two tanks. I tried for two weeks. I guess I should order more crypto pro (quinine sulfate) :/
