totally upto you. i have gravel in my bettas tank.
it's not unusual for a fish to play with his rocks.
my betta bowl has sea glass which is really dull glass so it wont cut itself
A betta is best as a solitary fish and it would be better to remove it from your main tank and give it a small tank to itself. You can buy very inexpensive betta tank kits for one betta.
They sorta can it depends on what color they are and the decorations and gravel. My betta is pure blue and it blends in with the gravel since the gravel is blue and some of the ornaments are blue.
I have always had gravel at the base of my Betta breeding tanks. The male will collect the eggs before they reach the gravel provided the tank has at least 10 inches depth of water.
Bettas can be kept safely in a gallon or more, depending on how active he/she is. If you want your betta to be really happy, get a 5+ gallon tank. Any size gravel/rocks will work, and my betta seems to like the plants I added. Remember, bettas like roomy habitats.
Yes. Bettas do best in a tank that is well planted and also has floating plants too. Best size tank for breeding them is 18"x10"x10".
If you have sharp or jagged rocks or gravel at the bottom of your tank could be rubbing out on turtle's legs. I suggest that you put some smoother gravel in or just take out the gravel or rocks!
All they need is a tank some water some rocks a plant and to be feed.
I am not an expert, but i would imagine they can by sucking them up. My advice would be to put less food in the tank.
No, gravel covering the ground of the tank or bowl will do fine. If you can fit them, they might also like an aquarium plant (living or plastic).
In their natural habitat they live in puddles in Asia.But in a fish tank I would put some smooth gravel with one or two fake plants.
