nice they look beutiful.... i heard that they are supposed to have sand, or at least gravel, because they borrow. not saying what your doing is wrong but thats just what i heard!!
yea i find my black rays are really aggressive during feeding times even though they just arrived 2 weeks ago. then again they were captive bred so that explains why they adapted a lot faster. marble was wc. finally got him eating prawn after a week of starving but he doesnt eat a lot of it yet.
marble is 8 inches
male leo with big dots is 7 inches
female leo is 5.5
hoping to mix this trio with my henlei sp when they catch up in size.
