Mine eats one time a day and 3 little pellets each time. The water should be changed once a week and all the gravel and plants rinsed out too- and I usually fill a jug with water 3-4 days prior to Sunday (which is bowl changing day) so the chemicals get out of it prior to putting the fish in it....my friend uses distilled water for hers-she has had hers for over 2 years now-I don't use plastic plants, I have a real plant in the borl with our fish-its not one of those tiny bowls, its like one of the goldfish type bowls...
Hermione Granger seems to be doing well with this system so I will keep with the recommended system.
"The beauty about betta fish is that they dont need a large tank to survive, they can cope quite well in a small bowl or those hexagonal fish tanks with no requirement for a filtration/aeration system running. This is because betta fish can live in water with low oxygen content after all, they did originate from the rice paddies of Thailand and Malaya. Keep them in a warm area they are tropical fish! Whilst I did keep my betas in little jam jars, now that I am older and wiser, I find it rather cruel to keep them in anything smaller than a small gold fish bowl
The advantage of keeping your bettas in a tank rather than a bowl is that you can now decorate his surroundings and the likelihood of him getting sick from you neglecting to change his water often enough is smaller. And there are some betta owners who will swear that having a tank system with a full on filtration system running does seem to make for a happier fish. Contrary to popular belief, you can keep betta fish with other fish, just not another betta! That way you can really see the full splendor of your beta when its flaring his fins and carrying on! And yes, as in most species in the animal world, its the males that are the dressier gender all the betta fish you would find in pet stores would undoubtedly be male, the female beta is a bit on the dull side. Generally, the smaller the container for your betta fish, the more likely you need to do frequent water changes. They arent particularly fussy about food, you can feed them once a day or twice if you feel the urge to. There is even specially formulated betta fish food now available! Dont overfeed because it would foul up the water and whilst betas arent too fussed about a bit of organic matter in the tank, it would be advisable to change the water at least once a week. Just remember to use pre-aged water (not straight from the tap) preferably left for at least 24 hours to let the chlorine dissipate or use one of the water agers on the market if you want to speed up the process.
What about those funny bubbles on the top of the tank that the betta fish seem to be making continually? Well, thats just his way of making a nest. You see, in the wild, male betta fish make these lovely bubble nests and then when a female comes along, theres a tribal dance routine with a lot of flashing of his fins and when shes suitably impressed, she will spawn and he will fertilise the eggs as they are laid. Then, the loving daddy that he is, he will pick up those eggs in his mouth and place them in his bubble nest. Thats the end of their brief interlude together and just as the black widow spider will turn on the male after relations, so will the male betta turn on the female if she doesnt turn tail and make herself scarce! The male beta fish will then care for the eggs till they hatch
after which he may choose to devour some of his young
so much for paternal love hey? Read on about breeding betta fish."
