personally, i would add some rocks or driftwood to the bottom, but in the end, it's totally up to you... that looks like a great tank to start with tho... what size is it?
Well it's a 180. The tank below it is my diy 75 galon wet/dry. I am finishing up polyurethaning the outside cabinet pieces. I made a canopy and sides going up the glass too. That should look great. A few more days and I will be done.
I am getting the Caribe Tuesday or Thursday - 10 of them from Jeff Rapps.
Is it better to have rocks and such for the Caribes to establish territories or just have a plain sandy bottom to help keep down aggression among the fish?
dang, you have so many options with newly stocking that 180. i would definitely go with a mixed pygo tank. the way you have it now kinda looks un-natural, unless you could lower that driftwood a little more and like JoeDizzle said to add some on the bottom.
