Hello I had an empty tank so I decided to do something creative with that, I want to have african cichlids may be a julidochromis or other smallcichlid so I thought of something that was functional and attractive, one of the ideas that I had was a Mario Bros the other was a shingeki no kyojin tank, but I chose the first since the PVC pipes simulate the caves from the native habitat and Mario is really popular.

I take the idea of an essay on the reproduction of the cinotilapya frontosa where the pvc pipes was used as caves to reduce their aggressiveness and some ideas for the desing in google.

Step 1: Do a Model

I use PS photoshop to design the model and put into full-scale all the decoration.

In the back pipe I hide the heater and in the front pipe I did a mini filter.

Step 2: Materials & Tools

Fish Tank
and all the supplies for the aquarium (filter, thermometer, heater,antichlor, etc)

PVC pipes

PVC fittings

Acrylic paint

Adhesive paper

Scotch tape

Brushes

Cutter, Xacto Knife or Scissors

Printer

Meter

Step 3: Cut and Paint

Just cut the pipes and the fittings as you want you can use a handsaw after that you need to clean it very well.You can use any paint acrylic paint this paints have water-resistant when dry, epoxi or one with waterproof just check if they are not toxic after drying, anyway I recommend you test the paint with the leftovers of the pvc to look the final appearance and know the drying times also you can use a test fish like a betta to check if there is any problem and for cycle the aquarium.

Step 4: Print and Paste the Decoration

I use normal paper on the clouds and the floor, after cutting it I used adhesive paper for a waterproof just in case if it get wet and scotch tape to paste it above the aquarium.

In the background you can use 1 poster paper and paste over it the letters if your tank is larger than a letter sheet, if not just print all in one page.
