Very weird problem I'm having. I have a tank with two cardinal fish, two clowns, a blue hippo, a powder blue tang and watchmen goby. The problem I'm having is I put algae in the clip everyday and the goby swims up to it and grabs it. The tangs will swim over and try to have a tug of war with him. So I decided to do a second clip on the other side and the goby grabs both. I feed them once a day and all the others seem to be fine. I'm worried the tangs are not going to get the algae they need. The goby is very active in the tank and I love his personality. Not sure what to do about this.
