I had a 18' x 4'x 3' glass saltwater aquarium in my old shop location. It had recently cycled and it had 6 black tip sharks, 1 lemmon shark, 2 huge parrot fish, and a show size Maculosis angel. THere were also several smaller fish like tangs, etc. The company I hired to help finish installing all the trim on the aquarium stands shot a nail into the top of one of the side panels of glass, knocked a large chip out of the glass but it was hidden by the trim. Naturally I was not informed this happened. Withing a week a run in the glass started and the pressure from the water put a large diagonal crack from top to bottom. It was fortunetly right at one of the center braces so the tank didn't come apart. I put a piece of duct tape over the crack to slow the leak (it was spraying out water pretty bad) and put every submersible pump I had in the shop in the tank to drain it fast, I was scared it might come apart. The largest aquarims I had to put the sharks in were only 125, these sharks were 18" to 20" and would not make it in them. I had a 300 but it had copper in it (copper kills sharks) TO save the sharks lives I GAVE THEM AWAY to my service accounts that had large enough aquariums to house them. (Have you priced black tip sharks?!!!) Two died, the lemon died, the show maculosus died, one of the parrots died, sold the other one. I never had any intention of selling these fish, it was a big cool display tank for me to have some fun with. Talk about a huge dissapointment, My dream aquarium was broken, my kick ass (and expensive) fish collection was gone, I lost my ass financially giving them away. TO add insult to injury, I could not get the company who caused the damage to pay for it. A bout a year later I patched the glass and filled it back up but never got it back to the way it was. I moved out of that building a year or two later and sold the glass.
I have some picture of the tank during the assemble of it and after it was up and running. I'll scan them in and put them in my gallery this week.
