It is particularly important to provide growing fry with clean water in order for the fry to grow properly. A buildup of chemical secretions in the water from the fish may induce stunting, though there is great debate over that. Despite the debate, most knowlegeable fish keepers prefer to keep the water clean through partial water changes (PWC's). The trouble with changing water in fry tanks is that there tend to be many of them and they have no problem swimming up the hose and down the drain.

I continue to see questions like this on yahoo answers about changing the ph of your aquarium. New fish keepers will attempt to alter the chemistry of their water with whatever potion they find on the fish aisle of their pet store. The reality is that almost anything you do to change the ph will be worse for the fish than the ph to begin with.

This article aims to list some best practices for designing and maintaining filtration systems for freshwater aquariums. Some or all of these may not apply to a given circumstance or size aquarium. This article is an extension an improvement of the earlier article on Rena Filstars filters.
I put some duckweed into the 55G tank in my office about 3 weeks ago. As of late, the tank is nearly overrun by it. Therei s a thick mat of the stuff covering about 60% of the surface of the water. I was looking in and saw a swordtail fry. I looked closer and saw dozens of them hanging out in the duckweed. Apparently floating plants really are good for raising fry. Up to now, I had been moving my fry into a breeder net. I decided to leave them in the duckweed to see how they do.
I am going to try to get pictures tomorrow.
