Planaria question?

I have planaria in two of my tanks. I was just reading up on them as to what causes them, if they are harmful and other info. What I've read is left over food stuck in the gravel. So here is my dilemmas:

1) One tank does not have gravel, it is bare bottom, and has left over food cleaned up twice daily because I have a batch of Angelfish fry in the tank. Where did the planaria come from in this tank?

2) Second tank has no fish, thus, no food. Only a couple of snails and some live plants. How are they in this tank?

They look soooo cute!

They don't only feed on excess food but also excess waste, bare bottom tank or not they survive, they are harmless, with baby fry I am sure they get lots of extra food and your snails create waste just like a fish, I have heard of people deworming the tank but in my opinion it just doesn't matter that much.

Good to know! Glad they are harmful and nothing to worry about!

Haha that pic is funny

But they are a nuisance and cosmetically disgusting. It's a indication of need to change something in your fish routine. And need to do hydrogen peroxide solution method when new plants acquired.  Sometimes planaria hitchhikes from plants. [You must be registered and logged in to see this link.]

No new plants in either tank. One tank has no plants at all. I'm guessing me feeding 3 times a day for the fry caused it in the one tank and the snail poop did in the other.

Gotta love freaking auto correct   

are you sure there planaria and not detritus worms??

Ya know from reading it to it. I'm not entirely sure. They are too small to determine well or even get a picture of but they don't wiggle as described of detritus worms they move like an inch worm.

I got over run with detritus worms once you have them they are hard to get rid of you can maintain the numbers though. From what I've heard the planaria have the arrow shaped head the derritus worm is brown/red look like pieces of thead you will see them free float after a gravel vac or stuck on the glass tops but most of the time they are out of site untill you are over run by them. 3 or 4 days of gravel vac will take them back to the minimum. Good luck

Just follow the instructions from this site.

They are only on glass and in the water. None above water line. I do not see anything brown/red colored coming from them. If they are jot harmful I don't want to do anything about them since there are sensitive fry in the tank.

once you get out of the over feeding stage with the fry the problem will prob fix itself.

lots of water changes will help reduce the excess waste and help to reduce down the planaria population

i have some in my smallest tank, and they don't seem to do any harm to anything. I don't find that they are that disgusting looking, so I never tried to get rid of them, just stopped feeding as much

Yeah they aren't much of a concern to me now that I know they aren't harmful to the adults or fry. You have to look for them. I wouldn't have noticed them if I wasn't looking at the tiny fry.
