OK so i have a 55 gallon set up (stocking in sig.) and these fish will out grow this tank so my lfs is having a sale and i want to buy another 55 and join them together to make a tank measuring 48x20x26. has anybody done this before?
sweet idea.
very possible. do a search on this site, its been done before.
filtration expansion, u adding a sump?
what filtration u got already?
what are u gonna do with ur fish while ur making the tank changes? im not so sure how long it will all take. 48 hrs?
sounds like a good idea and might be possible. but if it doesnt work than your out 2 55gal tanks. why not put them end to end? then you would have an 8ft tank! the fish would probely do better in the wider tank you want though.

I removed two long sides, cleaned the edges and siliconed them together 1/8" apart and clamped with bar clamps, then siliconed a 4" strip of glass centered on the new joint and clamped it in.
I made a new top & bottom brace out of angle aluminum
Keep us posted w/pix,
