Check out my friend's website- bettafishstream.webs.com
Asia#about any where. lots of people have beta fish as pets.
breath through their gills!
If it is like a black clump then its your fishes feaces(crap).clean it out
They live in stagnant ponds and rice patties in Southeast Asia.
CLEAN HIS WATER AS SOON AS POSSIBLE!!! Ammonia is produced from the fishes waste. It is toxic and will kill your Betta fast!!! Do regular water changes.
it depends some fish can be less aggressive than others i had a male Betta that lived fine for years with gold fish
If this black ink is comming from the fishes vent (anus) you need to do some more water changes and also improve the fishes diet.
You don't trim any fishes tail. If you do your fish will undoubtedly get fungus and die.
You can fit one betta in a 1 gallon tank, but nothing else.
Fishes are loosing their habitats because of the people.They go to the beech and throw the waste materials in the sea and play that "The waves will take this away with it "
