I'm new here, and thought I'd throw all my questions in at once. 
I have a 50g tank with a fluval 303 and an aquaclear 200. The salinity is set to 1.0010. I have a 1 1/2" GSP and a 1" figure 8, two 3" monos, and a 4" columbian shark.
My first question is about the columbian shark, (five fin shark, black fin shark,...whatever their called) This is my second time trying to keep a pair of them,...the first pair lost all their color, and died in a month,...and the same happened to one of the second pair, while the last shark has lost a bit of color but seems to be okay other than he has not been active at all since his buddy died about a month ago. He just sits around, should i get him another one.
I'm also starting to have a horrible algae problem, i have white gravel which is slowly turning green. The stuff on the glass is not so bad, as it scrapes off no problem, but my gravel vacuum does not pick up the algae. As far as i know there are no algae eaters the survive brackish,...except i've heard Mollies will eat it, will they survive in my tank, and would a pair of Mollies eat enough for it to be worthwhile getting them?
My last question is that my puffers don't seem to grow too fast. I've had them for about 8 months, and they've barely grown, other than rounder. They eat anything i put in (flake food, pellets, guppies, ghost shimp, snails, salad shrimp, and i recently tried fresh mussels, which they loved but it seemed to have left an oily residue on the water surface) Are all of those foods okay, and are they normally slow growers?
Okay,..thats it. Any suggestions would be appreciated. thanks.
