A small fish bowl is bad for any fish.
You need minimal 5 gallon for a single betta.
You need minimal 20~30 gallon for a single fancy goldfish, 40~55 gallon for a single common goldfish.
Because fish produce ammonia and it is toxic to themselves. Goldfish has such large body mass, so they produce enormous amount of ammonia.
You must have a good filter system, and do a nitrogen cycle first before adding any fish at all.
It should be fine.
Betta, Goldfish, Minno
Betta fish are best as a solitary fish and are not compatible with goldfish.
Betta fish don't even think about goldfish they need 10 gallons each. If your bowl is bigger than 1 gallon a betta will do fine. Below 1 gallon get a ghost shrimp or snail
No.
None. The 1 gallon bowl is already too small for the betta by itself.
yes, goldfish and betta fish fight.One time I had 2 goldfish and one bit the other one and it killed it.Never have 2 betta fish in the same aquarium or bowl because they will fight right when they get in the aquarium/bowl!
No you schould not have that many fish in a one gallon tank. Thats the size of a big betta bowl. And because they are goldfish it is worse their poops are toxins
No, betta fish are tropical fish; goldfish are coldwater fish, this should be reason enough not to mix the two. The mixing of these fish would be irresponsible and could yield distatorous results. One reason not to mix them would be because betta fish are quite small; most don't even reach 1/3 the size of a goldfish (even when full grown!) it makes them very likely to get bullied by the other fish. Fin nipping can be a major problem and is dangerous for the health of the fish. Do all your fish a favor by not mix betta fish with goldfish.
it depends on how small the bowl is betta fish usually dont grow larger then 3 or 4 inches
goldfish. Definatly goldfish. Or betta
