What a great diy thread. Everything looks great. You can tell alot of thought went into how you were going to set this tank up. Glad to see its still up and running. Great to see rays in it again.
Was your first black ray that one from Fishhub?
Have you ever looking into Southwind Foods for there equivalent of smelt. If I remember right they had 11lb boxes for $17.00 or maybe vice verses. Keeping my rays was much more enjoyable after their food bill got cut in half or less.
Thanks for such a fun thread and a ton of great pics and videos.
