Hello need some help with my zebra danio. I'm new to owning fish and I'm unsure of the wellness of my fish. I can't tell if the fish pictured (https://ibb.co/dLQ6iG) is bloated or is pregnant. I just had a neon tetra in the tank die from swim bladder disease so I want to be cautious. It was earlier hiding in a cave in the tank but after removing the cave it is back swimming with my other damio. The tank is 10 gallon with the only other fish besides the pair of zebra is a female green swordtail. Thanks in advance.
