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.
a gallon
yes.
yes
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.
you take the bowl and put the fish in it and put the beater in it
