Question

my fish are in another tank just now cleaned the gravel out too but when i put the new water in thats when i found them floating is it safe too put my fish back in the tank
i have seen some other similar questions some some very difirent answers but just want to be sure as i may well have them in the other tank too

Answer 1

Probably just harmless planaria. My guppy tank had a bad case some time ago. Cutting back on the amount you feed your fish will do two things to clear them up. First, it will cut off the planarians' food supply. Second, it will motivate your fish to eat the little buggers.

Answer 2

These are only planaria if they glide along the glass or gravel, much like a snail would. If they swim or wiggle in the water, they are something else.

The good news is, that if these are large enough for you to see without using a microscope, there's very little chance that they're parasites. They're most likely harmless nematodes that are present in every aquarium (most people just don't look that closely) you can compare them to photos at this website to be sure: http://aquarium-answers.blogspot.com/2007/03/trematodes-and-nematodes-in-fish.html. I personally wouldn't worry about putting fish back into the tank.

But this doesn't mean everything's okay. I agree with the other answerer that said you shouldn't be removing the fish when you clean. You should only be changing 1/4 of the water when you clean, but you should be doing this on a weekly basis. And you should be using a gravel vacuum to remove wastes (feces and uneaten food) from the gravel, so it doesn't build up. As this stuff decomposes, it creates ammonia and nitrite which are harmful to your fish - even in a cycled tank, this stuff will increase the level of nitrates, which are less harmul than ammonia and nitrite, but which can still kill your fish if present in a high enough amount. If you're seeing a lot of the worms, this is because they're using all the debris in the rocks as a food source, so removing more of this will result in fewer of the worms as well. Doing 25% water changes weekly stresses your fish less, since they don't have to be moved, and the temperature and water chemistry change less at each cleaning - far better to have small, frequent changes that few large ones. It also means less overall work for you.

Answer 3

if you take your fish out of the tank then you are not cleanning it right that way is hard on the fish and remove some of the things the fish need in the tank the worms are common and i think you will find your answers here please more about cleanning your tank and its upkeep http://www.oscarfish.com

Answer 4

DONT put your fish back. They can kill your fish... I learned that the hard way... I have to spend money to cure my fish. Okay clean your fish tank and add new water.
Dont forget to:
1.Leave the water out for about 2 days if its over 1 week throw it out!
2.Wash the tank with warm water No Soap!
3.Change filter if needed.
4.Put special conditioner.
5.Enjoy and love your fish.(hey they need love too people) <: )
