Danios are an easy beginner fish that does well in a community setting and makes a brilliant schooling display. The Longfin Blue Danio has beautiful colorations that will shimmer in your aquarium! They can be housed in really any quantity but keep in mind the larger the school then a larger tank is needed. They do exceptionally well in planted aquariums with darker substrate but can thrive in tanks without. Provide an aquarium with higher flow to mimic their natural habitat. The Longfin Blue Danio will accept just about any food that is dropped into the tank from freshwater flakes to frozen meaty foods.

ACCLIMATION: Avoid exposing new aquatic life to bright lights after opening the box. Turn off aquarium lights prior to floating aquatic life. Allow the sealed bag with your new fish to float in your aquarium for at least 15 minutes (but no longer than one hour) to ensure the water in the bag matches the temperature in your aquarium. A bacteria booster addition can assist with the addition of new aquatic life. Petco offers free water testing in store to determine if your water is safe for the addition of new aquatic life. DIET: A well-balanced diet consists of a variety of flakes, pellets, freeze-dried and frozen foods, depending on the species. FEEDING: Feed sparingly and no more than fish can eat in 1-2 minutes. Overfeeding can quickly foul the water, especially in smaller aquariums.

I have a freshwater fish in my aquarium that I cannot identify. It resembles a Mosquito fish but is lighter in color, thinner, swims differently, and has what appear to be sparkles on its sides. I caught it with a net in a school of mosquito fish but it is different. it was the only one in the school that looks the way it does. I found it in the shallow part of a lake in Florida. Please help me identify it.
I am not able to ID my fish. It seems to belong to the family of snakehead bettas. But it is yellow in colour. They belly is a shimmering yellow gradually getting duller towards the tail. the tail and fins are yellow with red borders. Its eyes are blue. It seems to be enjoying staying at the top most of the time. Its not aggressive. Please help me ID my fish
I got 3 zebra danios and 2 leopard danios at petco and in about a day of having them one died. the next day another dies with a strange white spot growing on it. it was not like cotton through which I hear is a disease. my tank is a 20 gallon and before I introduced the new danios I had 3 pearl danios and 2 plecos and the were doing very well and seemed to be in perfect health. well one of my pearl danios died after the new fish came to no obvious elements. and now my 2 plecos died.the same way
My betta is a baby boy (4monthold) When I first got him he was red with white. 2 months ago his growing fins began becoming blue. Abt 3 weeks ago I see that he began losing his color a bit& began becoming kind of transparent, so I took the water to get checked& the water was good but the store couldnt check for ammonia cause they had ran out of that test(water has conditioner). Last night I notice that he started getting a shiny silver color on 1side of mouth& in gill. But he is acting normal
what kind of fish are these? and would they be good with a male betta

Hi, In my tank I have 2 danios, 1 ghost catfish, 2 mollies, 2 tetras, and one baby ballon belly Mollie. One of my Danios constantly chases the other. I can't tell if they are playing or fighting, because they aren't hurt in any way, but the one getting chased is constantly hiding. One of my tetras has picked up similar behavior. The danio that is chasing the other is significantly bigger than the smaller one. Plz help, thanks
