Best fish for coral frag tank?

[LAA]

Hey everyone! Setting up a 20 gallon long coral frag tank. (Has been cycled for a year and a half. Used to be my main reef tank. Upgraded to a 125) so I was wondering what the best fish for a frag tank are. Thx in advance!

(current stocking, 2 clowns and a lawnmower blenny)

A wrasse will eat any pests that might get into your tank.

Small wrasse, like pink streaked. A carnivore for bad guys.

Would a yellow corris work? Or to big for tank size. I have a 125 gallon as mentioned Once it gets larger

I've seen several LFS's use springeri damsels in frag tanks for pest control also.

Yellow corris will get 5 inches, but that might take a couple of years.

Yeah so wrasse ideas for 20 long? That aren’t crazy pricey

I'm using sixlines in mine. Nice size and they are always hunting.

Yellow coris needs a bigger tank. Mine is 6 inches long. I think a 6 line is best, because it eats everything and doesn't need sand to sleep.

Six or 8 line wrasse.
Snails for algae.

Pink streaked if you can find it.

Pink streaked is perfect if you can find one. Stays very small fully grown.

I use yellowtail blue damsels. Shrimp and crabs will pick stuff off of frags too.

Ok thank you all! If you think of anything else let me know. My LFS doesn’t sell the pink streaks but does sell the 6 line. I heard they were bad tho

You’ll most likely have to ask a LFS to special order a pink streaked, as they aren’t as common. The nice thing about them is they stay a little smaller and a lot less aggressive than six-lines.

...its a coral frag tank. Lol

 

[Doctorgori]

mollies ain’t bad

I agree it doesn’t matter if it’s the only fish in there, but going with a pink streaked gives them an option to move it to the DT at some point in the wrasse’s lifespan if desired, without aggression issues.

I have one in every tank. . I found myself with flatworms in the frag tank and springari in there, Was not doing anything about it. Swapped it out with the one from the display and that thing Eats!!

My permanent residence, as I said are a springari and lawn mower blenny.
