White specks... Not sure?

Not quite sure what this is... (will try to take pics but they are extremely small!)

On the glass of the aquarium there are white specks everywhere... When I got up real close they moved around on the glass... This might be a long shot but I've had 2 Neon gobies in my tank for the last 3-4 months and this last few weeks they have been horribly aggressive to their burrow they built under a rock. as of the last few days their aggression died and they went back to cleaning and being normal.(upon having white specs magically appear) and my algae blenny has been insane about trying to get in their burrow.

Is it possible that they could have reproduced!?! The gobies are always around each other for 90% of the time and my mom said they look like they where humping each other. lol. Im unfamiliar with this so throwing it out for any advice to what it could be!?

 

If they look like white/grey colored slugs(snails with no shells) and have an arrow shaped head, those are called planaria. Usually you'll see them sucking on the glass.

If they look like a little white colored squiggle worms, swims in an S shape, or looks like a piece of hair on the glass, those are some variety of nematodes. They're harmless as well. a lot of fish will eat these when they see them.

Usually both kinds will show up in a tank that the fish are being over fed, or there's not enough water changes. They love all the excess food left in the bottom of the tank and in the sand. To get the population down, takes some time, but cut back on your feedings. Feed only what the fish will eat in about 3 minutes, net out any uneaten food. Even skip a day during the week. The fish won't starve. And, be sure to do weekly water changes. They are always there but water changes and not over feeding will keep the amount of them down.

 

just pods

 

Theres been a debate about over feeding with my fish, However in the amounts i feed, they consume the whole meal each time in under 1-2 minutes. not leaving a trace, even with flake or brine/mysis. Even the seaweed I feed them is gone. When I wake up Ill check on the body shape of the critters to see if it matches anything, But they seemed more round with a small tail almost like...

:d would be neat if they were pods!

 

Do they move?

 

Any more info??? Did you have a close look???
