How do I get rid of these.

I have posted a picture of these before and I am still having a problem getting rid of them. I went to the lfs and they sold me a hose to suck them out . Yesterday I did it 3 times and there is so many of them, is there a different way to get rid of them. I have increased water changes to try and limit waste that they may be feeding on. I just don't want them to take over the tank.
the little yellow worms at the bottom.

 

Can't really see them. But they're probably flatworms. Checkout a product called Flatworm exit.. Check it out on google. Never used it myself, but I've heard it does the job.

 

As you probably know, what you can see is a small percentage of the population present.

Some are photosynthetic and you can try a complete blackout. With that large of a population I would do the research on Flatworm Exit and try that.

Wrasses, and damsels are hit and miss. Sometimes if you reducing the amount or frequency with which you feed they may be more likely to start eating them.

If you go with Flatworm exit, you need to be aware of what to do prior to treatment, what to expect to see during treatment and what to do after treatment to dilute the chemical from the system as well as the toxic chemicals released by dead FW.

Good Luck.

 

I have heard from some other people that it doesn't work. Is it coral friendly.

 

Yeah, they look like flatworms. I'd treat with flatworm-exit and dip all of your corals in CoralRX.

 

Try a Coris wrasse then.

 

It's the starfish, snails and crabs that seem most negatively effected by it.

During treatment they look very stressed, after the water change and the running of new carbon they usually spring back.

Some FW, are developing a resistance to it, so some report. If you treat per the directions on the label, you may have to repeat it the treatment, but with the population you have I would sure look into it.

 

What is a complete black out, just turning the light out for a period of time? How long and will that do anything to the two fish i have (pj cardinal and fire fish), snails , hermit crabs, peppermint shrimp, and corals?

 

I've done ablackout for GHA for 3 days, although I had moonlights on. That is what I would recommend. Remember not all FW are photosynthetic so its hit or miss...I would really just dip in CoralRX, I've seen flatworms drop off frags like flies using that.

 

I have a 29 gallon nano cube. Is there something I did to cause the infestation?
