hi the only fish you can keep in a bowl with out a fiiter and a heater is the buitiful BETTA they can have it but they dont need it. My betta actually hates heaters and filters he love just water. Gold fish need filters but bettas are really hardy and just never put two males togeter the will fight . Hope this helps :)
Cut Bamboo will float but if you can weigh it down at one end somehow and then bury the weighted end in the substrata it can be quite an attractive and effective addition to the decor. Angelfish and Discus will even spawn on it. Bamboo will not live and grow in the aquarium however because it is not aquatic and it will eventually drown.
A fish bowl is not a solution its what you keep your goldfish/ beta fish in :P
it depends how big the fish bowl is
The cheapest way to keep a goldfish is to keep it in a fish bowl.........as long as the bowl is big enough the fish will be happy there.
Betta
I guess you mean Puffer fish. If so, then the answer is definitely NO! IMO there is no fish that should be kept in a fish bowl.
No
The best candidates are Betta fish and Paradise Gouramis
As long as that plastic bowl is large enough to fit in x amount of fish you have and you fill it with an appropriate amount of water.
Platys can sometimes be kept in a bowl, if the bowl is big enough and in a warm enough area. Generally, though, fish bowls should be banned and not used.
Although it may well be possible to keep one for a short time (1"of fish NEEDS 1 gal of water)I believe it is cruel to keep any fish in a 'fish bowl'. Even a Betta.
You don't. You put it in a pond. Koi grow to over 24". To keep one in a bowl would be terribly CRUEL!
no. a fish bowl is way way way too small for any fish, let alone a group of tiger barbs and mollies.
