What is growing in my tank?

zrquincy

I recently bought a fish and 3 cichlids to go with it. I feed them blood worms and spirulina pellets. So far everything has been running smoothly, this morning when i turned on my fish tank all of the bits of food that weren't eaten had this spider web looking stuff on it and i was wondering what it is and does it harm my tank?

I wasn't sure how to preview the pictures so here is the link.

White fuzzy stuff is usually a fungus.
Do you vacuum the gravel when you do your water changes?

I would definitively vacuum the gravel and get any of the uneaten food out. If it forms fungus on it it can be a real pain to get rid of. Once the fungus is formed it can spread through out the substrate and other parts of the aquarium.

I haven't vacuumed the water yet, i just got the tank a week ago and got the fish last friday.

I would still at least try and get the un eaten bloodworms out of there.

Can it hurt my fish?

I have a 29 gallon fish tank that has a mold problem, i just vacuumed it and was wondering if there is a quicker more effective way to take car of the mold problem..

Are you sure it's mold? It could be a bacterial bloom. A picture would be helpful if you can post one here.

Reduce the amount of food offered and vaccum the gravel with each weekly water change.
