Yes. All fish can transmit certain diseases to all other fish.
Some diseases are species-specific but, like humans, sometimes one disease will lower the immune system, and give the fish other illnesses as well.
If you notice your fish is diseased or dying, Quarintine it in a seperate tank/bowl, with the highest quality foods and keep a close eye on pH, Ammonia and Nitrate levels.
Lots of things can happen! She can jump out of her bowl, fall while being placed back in her bowl, get one of the many diseases that bettas get (Pop eye, cloud eye, Tail rot etc.), she can be p;aced in a bowl with another betta and fight... What are the symptoms that you are seeing in your betta? When you find out, start a new question, explaining better. Natalie01
No. They will kill each other.
a betta bowl is about 12-15 inches in length and about the same in height
betta bowl. it is amazing
None. The 1 gallon bowl is already too small for the betta by itself.
Yes and no. Yes because they can comunicate and they will try to impress each other and that gives them exercise. No because you male might try to jump in your females bowl, but that probably won't happen. But it is better to keep there bowls beside each other because it is good for them.
No! You don't have to have a plant in a betta tank.
well if its a betta fish then yes, two male bettas in one bowl may result in one killing the other. you may also notice that even when there is only one male betta is in a bowl it will try to attack its reflection thinking its another male betta
Its ok as long as you let the water cool to room temperature before adding the water back to the bowl, or adding the betta to the water. Also, it is completely unnesseary to boil before putting in your betta's bowl.
yes.
I am no expert, but believe that betas are solitary and prefer to have a fish bowl to themselves.
