why is my water cloudy?
i've had a betta before and never had this problem.. what am i doing wrong? i just did a water change and the water still appears cloudy. i'm out of water tests so that's the first thing on my to do list for tomorrow, but what could be causing this?! and how do i fix this? i've only had hector for a few days and i would hate for something to happen to him. he is a muticolor marbled half moon double tailed betta and he's absolutely stunning.

he's in a two gallon tank (which will be upgraded to a ten gallon in a month or so). he has a filter, heater, and plants.
