My DIY background finally done in 75 gal tank

75 gallon tank for my son's flowerhorn (he outgrew the 50 gal) I made the back, the 2 sides, and the bottom look like rocks (in case they move the sand away - it will look like rocks there also!) He's a little pale.....but he's still getting used to his new surroundings.

Styro foam carved into shape, and then I added layer after layer of concrete. Once it is just the way I like it - you use gobs of silicone and silicone it into place. Then you "cure it" by filling the tank up, and draining the tank like a million times until the ph is stabalized.....and your done! If you did the sides like I did - you may want to spray paint the back and sides black so that you dont see the styrofoam. It's actually a fun and easy project - just remember to measure twice and cut once!!!! and use 100% silicone - as bathroom silicone is toxic to fish. Give it a try!

Thanks all, now my flowerhorn can continue growing....... I've never had one before - I'm amazed at how fast they grow! Mine went from 1.5" to 10" in like 4 months! And his color is awesome, and he is very gentle toward everyone (except feeders!!!) He's more like a pet than a fish - my son really likes him! Dane, as for my styrofoam - I had a few large styro boxes laying around, and so I used them - but Lowes or Home Depot or even arts and crafts stores all sell sheets of styro foam. On my first background on my 210 gal tank I used plankboard ( alot thicker) If I was going to plan on doing another one (and had to buy material) I would use the thick green styrofoam sheets that they sell at arts&crafts stores (if the concrete ever cracked off - at least green would show thru and not bright white!) Good Luck - and post pictures!

Update: He has continued to grow and grow, and is now about 14 inches!!! So I've updated again to a 90 gal tank. No DIY background in this one, this time I made corner overflows to hide all of the tubes and wires, so all you ever see is the fish and decor. He seems to love it! I will post new pictures when I get a chance (my son wanted Bikini Bottom - Spongebobs' town - so that is the new theme that I was going for....looks pretty cute.)
