flatworms

[Delphinus]

On the advice of Seahorse_Fanatic I picked up a yellow canary wrasse (Halichoeres chrysus) when I noticed flatworms in my tank around Christmas time. Within a month there wasn't a flatworm to be found in the tank.

And, it's a very pretty fish.

Also called a yellow coris wrasse but it's not related to the Coris family of wrasses (which get huge).

I wasn't saying that you could kill them with nutrient control. I just think that tanks in nutrient overload are much more susceptible to flatworm plagues. I do however think that you can manually control the population if you're willing to rip the tank apart completely. Most people want an easy solution though.
