Angelfish are a schooling/shoaling species and should be kept in groups of no less than 5 if you with to avoid fighting and bullying problems in the growing young fish. 2 males will be OK until they reach breeding size and condition and then there could be fights as they try to mate up with females. I very much doubt if you can sex your angelfish anyway. It is extremely difficult. Particularly when two females will commonly get together and spawn.
I dont get it. Did your angelfish die?
No...betta fish are usually aggressive and might kill the angelfish.
No the beta will try to kill it
That will likely cause very few problems.
that probably wouldn't be a good idea.. the Oscar will probably eat it.
Clownfish and angelfish have different habitat requirements and behaviors, making it challenging for them to coexist peacefully in the same tank. Angelfish are typically larger and more aggressive, which can lead to conflicts with the smaller and more passive clownfish. It is generally not recommended to house clownfish and angelfish together in the same aquarium.
Angelfish are very aggressive fish. They are also very territorial. They want their own space and the whole tank if they can have it. I'd suggest that if you have a small 3 to 5 gallon tank you get a bigger tank as that size tank is too small for Angelfish.
Anything that's bigger than them. My angelfish is afraid of the light over the tank.
To maintain or gain leadership in an area, probably your tank.
If the tank is big enough. (40 gallons per dragon at the minimum)
Angelfish are clever fish, from my experiences if you put your finger up top of the tank they will follow it.
Yes, but if it is a female and a male, they might mate during mating season. But male and male or female and female are perfectly fine to live together, but they must be the same size or age because if not, the bigger snake will most likely eat the smaller one. Always make sure you have a big enough tank for two or more cornsnakes to be living in.
