http://forum.aqua-fish.net/ A forum devoted to aquarium fish, plants, techniques and fish keeping as a whole. en http://forum.aqua-fish.net/?topic=hello-i-amp-8217-m-ackerz#1 Iam 15yrs old and live in the U.k I have a extensive knowledge of fish(Unusual I know but it is my passion). I read Pratical fishkeeping every month, any rent books from the libary at home and in school, also I use many internet sites and over time I have become a Brainbox when it comes to fish if nothing else. Is there any request for information on any types of fish just post a reply and I will put it on the forum. (or just add me as a friend) From Ackerz original post: January 3, 2007, 7:39 pm Ackerz 2008-05-01 http://forum.aqua-fish.net/?topic=hello-i-amp-8217-m-ackerz#2 Hi! I have a question that maybe you can help me with. I have a fishtank of mollies. There are very tiny, almost microscopic critters swimming withing the gravel of my freshwater fishtank. Do you know what these are? Are they harmful to my fish? jessyc76 2008-05-01 http://forum.aqua-fish.net/?topic=hello-i-amp-8217-m-ackerz#3 Those tiny critters they could be baby mollies or a many number of things without a picture it is immposible to tell I would advise you not to worry and continue running your tank as normal If many fish die from a unusal reason (apart from age) then either sen in a picture or get a professional from a shop to have a look. I would advise you not to panic, they are probably babies.
