Hi, I’ve had my 240l tank set up for around 6 months. I have 2 clownfish, a watchman goby and pistol shrimp pair. One of my clownfish seems obsessed with my watchman goby. The clown swims down to greet and rub himself against the goby everytime he pops his head out of his little cave. I don’t know if this ‘friendly’ behaviour may end up being ‘aggressive’ either by the clownfish showing authority or the goby simply having enough.Is there anything I can do to stop this? Thanks
