There should be no "arch" to any Danios back whether it be male or female. An "arch" in the back is a genetic spinal deformity cause by inbreeding.
yes as long as there are not any other males or female bettas
Forget about them being "glo fish". That is just SPIN. Glo fish are a genetically altered common fish made to glow artificially. They are in reality Zebra Danios (Brachydanio rerio). The females are slightly larger and plumper in the tummy than the males which are more slim lined.
GloFish are a patented product and breeding is restricted by law. GloFish are genetically engineered zebra danios. Breed them will not produce GloFish that are true to color. They will look like regular zebra danios. They are egg layers. If you have males and females together you will get fry.
Yes, they are both danios so they can mate. Make sure you have more females than males when you mate them!
Do you mean albino zebrafish, as in zebra danios? If so, not at all! They are a freshwater fish.If they are not zebra danios, I can't find them by the name "albion zebra fish," and I haven't heard of them.
yes unless the zebra danio can fit in its mouth
Zebra danios are not live-bearing fish, so they do not get pregnant. Instead, the female will lay eggs, and the male will fertilize them. The eggs will hatch about 2 days after being fertilized.
Yes, but not all zebras, some are female, some are male
i think they come from India or near there anyway
No killifish like to nip at fins.
Under normal circumstances zebra danios are not vicious towards anything. However if their diet is lacking in protein they could well do some fin nipping of any other slower moving fish.
id say guppies, they breed like rabbits
