Great new rockwork bro, I really like it alot. Love what your doing with the tank. And bout the Brine shrimp. I used to feed everything that but i was told on here it was not very nutritious , so i switched to Mysis shrimp. Try that
Make sure it isnt the large mysis though because i couldnt get my fish to eat those cause they were like 1 1/2 inch long and kind of big. Get the regular sized ons that are kinda bigger than brine shrimp. Well take care and hope everything stays healthy and looking beautiful for ya. I like all the caves you got in your tank
