No
None. Bowls are for soup, not fish. Put them in a proper 10gal tank with a filter & heater, plants, rocks & gravel. Add some snails & shrimp for colour.
it depends how big the hermit crab is or the fish bowl
you get a net to take out the fish and put it in a container while you're cleaning the bowl and put the fish back in when your done :) hope I helped :)
A fish will most likely die if you put a cleaning agent in its fish bowl without removing the fish. You should remove your fish with a net and place it in another safe container until fish bowl is clean.
you can put in sea snails and more brightly fish that you cant get with a heater in your tank
Being in a closed room with the heater on become stuffy an losers oxygen.
No fish. You can put them in one, but it is very cruel and inhumane.
yes
yes.
you take the bowl and put the fish in it and put the beater in it
It may be possible to keep 4 small fish in a one gallon fish bowl, depending on the type, size and needs of the fish you choose. It will also depend on whether or not the fish bowl has a filter, and if your fish can live without a heater. For example, because they do not get large, 4 white cloud minnows can be kept in a one gallon bowl with a filter and they do not require a heater. You can also keep a male beta or Siamese fighting fish with a few white cloud minnows; or 2 small goldfish which can grow too large or the bowl.
In theory, you could have a 2 mL fish bowl, but you could only put a very small fish in it. The 1 L fish bowl would be a better choice.
