I am very new at the hobby, and so far so good... I have 5 neon tetras, 2 albino corys, 2 sunset platys, 4 ghost shrimp, 2 snails, 4 danios, & a betta (I've moved him to a little tank since he got nipped by the danios!) in a 10 gallon tank. here's the problem, I got the tank almost a month & a half ago with no idea what the term cycling was (I thought just treating the water would be just fine!!!) everything was fine until a week ago when it got extremely cloudy, so i cleaned the water out. amazingly non of the fish died, & they all seem happy but the water seems to be clouding up again. why did this happen so late? now i don't know what to do since I got all this fish crammed up in a tank!! I love my fish & don't want to think about losing them, the reason why I started is to introduce myself to the hobby so I can get a 75 gallon for saltwater. the burning question: CAN I CYCLE MY TANK WHILE THE FISH IS IN THERE?! IS THERE SUCH A PRODUCT THAT WILL NOT HARM THEM?! PLEASE HELP I DON'T WANT MY FISH TO DIE!
