what freshwater tropical fish that look cool and are interesting to watch can you start with????

Thanks, J

The ones that you have in your tank are fine to start with since they are inexpensive to start with. How long have you had your tank? You will want it to cycle properly before you buy more expensive fishies :)

Just keep up the 25% weekly water changes, treat frsh water and do NOT wash the bio-filter in anything other than tank water. What i do when i do water changes is get a bow scoop up some tank water and wash it around in that than put it back into filer unit. The Bio filter retains all the good bacteria you need for you tank to stay healthy

The filtration system you have prob came with ur set up. If so, it is single pump, and contains to type of filters, one on the inner most section of the pump Probably has a blue mesh on it (which the water should contact first), the filter closest to the exit of the filtration sys. is a black mesh filter, this is the bio-filter and awhen the tank is cycling this is where the beneficial bacteria will start to grow.

The one you want to swish in water will have the sponge type stuff in it. I wash all my filter media in tank water. If you do then you will not harm any bacteria in any of the parts. I am thinking its the two blue that you need to be careful with.

Hope that made sense because I haven't had my coffee yet LOL

cool thanks people that makes sense now so do i change the filter media every two weeks or can it be longer because i only get 5 bucks a week.LOL
