I've had a 60 gallon freshwater aquarium for years. Then one day my red belly pacus went carniverous and ate the tails off of my gold tinfoil barbs, I said thats enough of this shit... tossed the fish and emptied the tank.
Now its a saltwater tank with 2 Percula Clown Fish, 3 Green Chromos, 1 Orange Spotted Goby, 1 Scooter Blenny, 3 Peppermint Shrimp, 2 Emerald Crabs, 10 some kind of snails that burrow into the sand, and about 45 - 50 small hermit crabs. Currently have 15 pounds of live rock. Going to add more soon when i find a good supplier, the stuff at the local fish stores isnt exactly what I would call 'live' rock at all.
I picked up a 100 gallon 'cube' tank a couple of weeks ago with a very nice stand & canopy for $400. Only catch was that I had to finish the stand and canopy myself because it was just bare wood. But that turned out to be kinda fun. Put 2 coats of stain on it, then 2 coats of polyurethane and now it looks great. Going to order a 'package' reef setup from
http://www.tampabaysaltwater.com because I read so much good stuff about them on aquarium forums. If thier stuff is as good as everyone says it is, then I'll order more live rock from them for my 60 gallon tank.
The cool thing about aquariums is that you're never 'done' with them unless you want to be. After I get this 100 gallon tank set up and running, I'm going to build simulated moonlight lightbars for both tanks using blue and white LEDs and set everything on timers. And maybe after thats done, I'll install ultraviolet sterilizers on both tanks and then I'll never have to worry about diseases or parasites. And then maybe I'll install water chillers so my water temp stays the same year round.
