I have a Strawberry Psuedochromis that resides in my refugium. When my water is at the high water mark there is about 1/8" flow over the baffle and a 1" gap on the bottom of the next baffle that makes up the return chamber.
The SP will jump the first baffle and then swim down and under the next baffle and hang out with the Mag 7. At feeding time when I add water to the refugium, it swims back and jumps back over the baffle to join the Sleepr Banded Gobis for dinner.
Now let's hear your fish tales!
