I'm a little bored, so I decided to do a post on creating a healthy, happy habitat for a
betta.
First, you'll need to buy a tank. Do NOT buy a bowl, a vase, or anything less than a 2.5 gallon! A 5 gallon would really be alot better than a 2.5, and if you get a 10 gallon, your betta will have a palace!
You'll need a filter and a heater. Bettas like to be kept at around 78 degrees, and they don't like alot of water disturbance from the filter, so take this into account when buying. Make SURE you don't go overboard with the equipment. A filter for a larger tank will cause too much water flow, and a heater that's too powerful can kill your betta by oveerheating the tank.
Also get some substrate. Don't get sand. If you get gravel, make sure it's smooth so it won't damage your betta's fins. Marbels or those little flat glass "pebbles" will work well.
Get some plants and decorations, too. Live plants will provide oxygen and absorb some
ammonia. If you get fake plants, don't get plastic! They will tear your betta's delicate fins. Get silk plants instead. Get a couple of structures for your betta to play with, such as a castle with large smooth-edged holes.
Take your tank & equpment home. Do NOT buy a betta yet! You'll need to cycle your tank before you put your new friend in. Set up the tank, plants, decorations, filter, and heater. Don't put it in direct sunlight. Research instructions for a fishless cycle, follow them, and don't buy your betta until you have 0 ammonia, 0 nitrites, and around 10 nitrates.
Make sure you aclimate your betta before letting him into his new home. If you don't, you risk having him or her go into shock from the change in water temperature.
If your new fish doesn't eat right away, don't worry. Give your betta a few days to settle in.
When cleaning the tank, never wash off the gravel, and NEVER use any soap on anything going into your aquarium. Use a siphon & gravel vaccuum and do a 25%
water change every week.
Have fun with your new betta!
