Painting Backgrounds Black.

So your considering painting the back of your tank huh, well this may help.

Firstly. why would anyone wish to paint the back of their tank at all, let alone paint it black?

Several Reasons.

1 - It provides a neutral background, allowing  the natural colors of fish, rocks, ornaments, plants  etc to stand out.

2 - Black is always in vogue, when has it ever been not cool? And it won't date even if you have that tank for years and that possibly helps with resale value in the event you eventually decide to sell it.

3 - Black will have the effect of camouflaging some of those algae and mineral issues as well as unsightly plumbing and electrical fixtures.

Paint Versus Backing.

1 - Paint is going to be permanent which is good or bad depending on your perspective.

2 - A tank is going to be extremely heavy. Water weighs 1 kilogram per litre, then add the weight of your empty tank, your substrate, rocks, etc and even a relatively small 40 litre tank could end up being around 100 kilo's.

Once its located and filled, you will not be able to access the back of the tank readily, so and background change is not going to occur without considerable effort, so it's advisable not to use anything your going to have to muck about with or change anytime soon.

3 - Adhesive backings can bubble and peel over time and paper has bee know to fade, making paint a very viable option for a long term background.

Whats Required?

1 x You bewt fish tank.

1 x Litre black paint of your choosing.

1 x Small foam roller handle, cover, and pan

1 x Paint brush.

1 x Roll masking tape.

2 x Metre long 50x100 scraps of wood.

As well as that, a drop cloth, paper towel, rubbing alcohol and something like an old sheet or towel to put under your tank will be required.


Never use cleaners on the inside of the tank.

Never paint the inside of the tank, fish are extremely sensitive to chemicals.


1 - In a well ventilated area, lay your drop cloth and on top of that your timbers to slightly elevate the tank so as to avoid sticking and to allow you to get under it easily when moving.

2 - Thoroughly clean the tank using water both inside and outside, making it ready for use immediately after painting. Clean that part of the tank you will be painting with the rubbing alcohol and paper towels, removing any oil, grease and chemicals.

3 - Mask the sides of the tank with tape to protect them from any overflow, making sure to firmly apply the tape to avoid paint seeping under it.

4 - Using the paintbrush, cut in the rim and edges of the tank and with this paint still wet finish the bulk of the area  with the roller, let this dry for about one hour.

5 - Repeat step 4 until the tank is a shade of black your happy with, but around three coats of paint should do.

6. Let the paint dry for around 24 hours before attempting to use it and remember, the paint will take about a month to fully cure and become hard, until then it's quite susceptible to scratching, so be careful moving the tank and setting things up.

7 - Carefully remove the masking tape.

Your now ready to set up your freshly painted tank and enjoy the fruits of your labour, enjoy !
