Stressed Yellow Clown Goby?

[Oscar]

Last week I added a yellow clown goby to my tank, only the third fish to date.

Back in July I added 2 clowns who at first hosted to the branching frogspawn. After the pulsing xenia forest grew in size both clowns started to host the xenia full time. Quite interesting to see their sleeping positions at night.

When the goby was added he immediately hosted to the frog spawn and was very well hidden. But the clowns were not impressed. They pestered the goby until he sort of gave up the frogspawn, although I still see him in there time to time.

Now the goby spends most of his time adhering to the back wall of the tank.

In hindsight I guess I should have waited until I had some SPS for the goby to perch on.

He is eating well but will he be unduly stressed not having an SPS to perch on?
