I have a 40 gallon breeder (perfect size for a tank), running, with stand, LED lighting, rock, corals fish, etc. I also have a 125 gallon lock stock and barrel for sale. What does this mean for you? You can move a 40 gallon already seasoned, leave behind the corals you don't want, and choose corals from the 125 as you like... Of course, price depends on the corals, fish, and accessories you choose. FYI, I'd do the 40 breeder with the stand, light, hang on back CPR fuge, the fuge light, chaetomorpha for the fuge, 2 pumps, sand, and water (keep the water to keep the tank seasoned) for $350. We can add rocks, corals, or fish as you wish. And, since you'd be doing me a favor by getting it gone easier, I'll go really easy on you with the coral prices. I have enough room in my 125 to keep the rock and corals you don't want.
