Hello fellow aquarium enthusiast's! I have a 47 gallon Salt water with 10 fishes. 3 chromis, 2 clown fish, one is a clarki and He is the biggest! 2 elegant black and white striped damsels. a puffer, a sea star and a striped blenny! Oh and i cant forget a 4 inch Royal Gramma! Having fun with rocks and new decor ( asian house with large opening, fish love it ). But how do I blow off my live rock? Also have one cobalt blue damsel,, Never do water changes but add 4 gallons of spring water weekly which is treated with conditioner.
