hi guys i posted a few weeks ago that i was going to buy a 40 gallon tank but i have made the decision to buy a 12 gallon instead. it is all set up and has been cycling for 3 days but the water is still not perfectly clear is this normal ?. the decorations i have in my tank are a fake long , a rock formation and some fake weeds i am going to get a live plant soon. what fish should i get to have a happy and healthy community tank. thanks for your help
