Hi, I'm new in the forum and in fishes as well. So I wanted to start with the smallest tank. I bought one 5 gallon aquarium, those that say minibows, and i set it up two days ago. It looked pretty nice, i also added a small trunk and some artificial plants. I let it run during almost 24 hr with the filter (included in the tank) and yesterday i put an electric yellow in it, which the store guy told. me would be ok in a 5-gallon tank. But now the water is kind of cloudy, kind of green or yellowish. IDK if it is the trunk or whatever cause i havent unplug the filter. also the fish is kind of shy, he doesnt want to swim around, always hiding in the trunk. Im thinking about taking the trunk out.....
