Betta fish bowls do not necessarily need to be very large due to their harsh living conditions in the wild; however, the bigger the tank is, the longer he will live and you don't have to clean the tank as nearly as often. Adding a live aquatic plant adds beauty and even more oxygen to the water, giving maximum health to your Betta.
They don't have to have very big bowls because they can live in very small spaces however, they are very energetic and love to swim around so if you want to keep two or three you might contemplate a big tank with lots of hiding places. It isn't a good idea to keep a male and a female together, unless they are breeding but, you can keep two females together peacefully. Two males is DEFINITELY NOT a good idea.
Bowls are absolutely useless for keeping any tropical fish in. To keep a Tetra of any species (they are all tropical) you will need a tank with a heater/thermostat, a thermometer, a filter, some substrate on the base of the tank, some live water plants in the substrate a cover glass and lights. The minimum sized tank to house all this would be around a 10 gallon tank. That would be large enough to house about 8 inches of fish.
Goldfish are messy eaters. They should have a bowl about 5 gallons or more, as long as you don't feed it to much.
the scientific name for the blood fin tetra fish is Aphyocharax anisitsi
no.
Yes it can
About $50 for a bowl- $150 for the whole fin
yes, but it may kill the goldfish
well, for guppies, if the small fin under the tail fin is long and ribbony, its male. if its wide like a tetra's, its female. ( Its the same for bettas.)
The females are a lot less colourful and are a little more round
The dorsal fin of a fin whale is typically 20 inches in height and ranges from 10 to 30 inches in height.
If the neon is in a tank with other neons then there is a good chance it will grow back. If your neon is in with other fish and larger fish there is a very good chance it will be eaten "Big Fish Eat Little Fish".
No, don't risk it. Serpae tetras are fin-nippers and they'll constantly stress out your Betta. Especially in a small tank such as an 8 gallon, I would find something else to go with the serpaes. (:
