So I have a grow out tank that is doubling as my plant quarantine tank. It currently has a betta fish and some Minami shrimp. So I recently got some plants in, and I've noticed that a lot of small white creatures have appeared in the tanks. Now I'm pretty sure this is just daphnia and some micro copepods the description on the page where I ordered the plants from said harmless insects so I'm not too worried about this at the moment. The problem is though is that the main tank that some of these plants are going to be going into I don't like seeing these little pests in there. I've been able to maintain a pretty clean environment as far as what's inside the tank.
So my question is this, can I use a fish like chili rasboras as a way of eliminating these pests? For instance having a nice group of chili rasboras in my grow out/ isolation tank would have would help deal with unwanted hitchhikers. Is it true that the chili rasboras or another Rasbora or micro fish can help deal with this? If this isn't a good idea then what would be a good idea for dealing with all these pests without being harmful to the shrimp, the betas, or the ancient fish when I move the plants over? But ancient fish I have in my main tank are black ghost knife fish.
 
Pics of what you want gone and pics of the tanks would help. I don’t know if rasbora are pest eaters, but they would certainly help. Loaches and dwarf cichlids would do similar.

Any small schooling fish would work. You can also dip the plants in a meth blue bath and then rinse in fresh water prior to moving them into the main tank. What fish do you have in the main tank?

Juvenile Black Ghost Knives are in my main tank. It is a species tank. Idk meth blue, but I have read about soaking them for a minute or so in a diluted bleach solution.

From what I can see, it's mainly daphnia. Probably some other small critters as well. It's kind of difficult for me to post pics. Mainly because I would have to post from my phone and the camera on it is horrible. The grow out/quarantine tanks are both 13g each with dirt substrates.
 
They don't really do anything, if anything the betta will snack on them between feedings and keep him occupied.
 
As said, any small schooling fish would eat them, I’d hate them to be a problem with the knives though.

That is my worry. I highly doubt they would hurt the knives, but why take the risk? I am hoping the betta's and chilis will eat them all so I won't have to worry too much. I know shrimp will eat anything, I've seen them take blood worms which was pretty cool to see. So I assume the shrimp will also take part in eradicating them. I'd be annoyed having to bleach bath the plants every time I want to move them, but if the fish can't eliminate them all, that's looking like what I'll have to do.

I doubt you’ll have to do anything drastic. In a larger tank the daphnia would be unnoticeable. I would think something like neons would be harmless.
 
Your knives would eat them.
