Temporarily keeping Six Line in Pico Tank?

[TheWackyWiz]

Hi All,

I've got a burgeoning rust flat worm infestation starting in my 6g Pico Tank and wondering if its possible/ethical to introduce a Six Line Wrasse to help put a dent in them? He'd only be in there until I can get the flat worms down to a population size where I can manage them with suction or potentially flatworm exit. From there he would move into my very stablished 20g.



Pico Inhabitants:
1x Skunk Cleaner
2x Astraea Snails

20g Inhabitants
1x Ocellaris
3x Thread Fin Cardinal
1x Chalk Bass
Tons of Rock work

Every once and a while my LFS has Blue Velvet Nudibranch's so that could potentially be an option as well.

I don't see a huge issue with it as it's a temporary situation. I would use a turkey baster to blow the fw off surfaces to entice the wrasse. Blue damsels have been know to eat fw as well.

No fish to be bothered by toxin I would probably just go flatworm exit ot similar. Do a couple rounds and be done.
Personally I would not add a sixline to a 20g, especially one that already has 5 fish. I like a sixline in every tank for pest control and have two but I won't be putting one in the 20g I'm currently stocking. JMO
