its looking good for a start but i would stack the LR better it just looks like its kinda lumped all over the place.... maybe make a cave in the structure somewhere?
i thinkyou have a pretty intricate desingn my friend, I like da fishies too. What other fish to do have in there besides the false perc? What is that goby?
if i remember correctly the rainsford goby, specificlly will only eat algae, i may be wrong but i am sure that is what i heard about them because i was lookin into buying one. and if there was no algae then that is probably the reason
