Well, now your done. You can use it as some weird sort of modern art(i still dont understand that crap), put it on your desk at work, or put it into y...
Step 12: Add to it
Put in about 2 or so inches of AGED aquarium gravel. The gravel doesnt have to be aged, but it will aid in biological filtration, due to the beneficial bacteria that grows in the substrate. Then fill it to within 1/2" with water treated with chlorine/chloramine neutralizer. Then you can add 1-3 ,depending on their size, ghost shrimp to the tank. You can feed them a SMALL pinch of very crushed fine fish flake, once every three days. Due to the extremely small bioload that ghost shrimp contribute to in their habitat, water changes do not need to be frequent, about once every two weeks to keep the ammonia at bay. Use a dropper every couple days to vaccume up all of the uneaten food at the bottom. And There you have it!
P.S.: DO NOT even think about putting a betta in this light bulb!
