Is this planaria? Infestation for months?

Hello all, long time no post.

I've been battling these little (harmless) tank creatures for a few months now. They just seem like little, slow-crawling white lines on certain parts of the tank wall -- namely, the front, with some on the back.

I've cut back on feedings, cleaned the tank excessively, and scraped the buggers out when I see them. Is there anything else I can do? My axolotl seems healthy and I've never seen them on her.

I wonder if they are limpets?

Hm, they do look similar. Those in the pictures seem slightly larger than what I have, but perhaps they could reach that size if I were to stop removing them.

Any advice on what I should do? Should I try to keep removing them? Will they die off? Are they actually beneficial? I read that they eat algae, but I haven't seen any algae in my tank prior to their appearance.

They look like planarian to me. If you look closely and one end has a triangular shape, they are definitely planaria. I can't get quite enough detail from the pic. Limpets have a round profile on the glass, and you can see the outline of their shell. I wouldn't worry about them. If they bother you, I have seen ads for planaria traps on Aquabid.com- I've never used them, so I don't know how much they would help. Picking up any debris that they can use as food will help, too. Here's a picture of a limpet in my tank for comparison, and it's next to copepods (cyclops) above and slightly right for size. They're not very big. Also planaria will slide around, while limpets move so slowly they don't look like they ever move.
