yes otherwise they will eat eachother
When angelfish lay eggs and you need to remove them for safety or breeding purposes, gently scrape them off the surface using a flat tool, like a credit card. Be careful not to damage the eggs, and transfer them to a separate, prepared tank where water conditions are similar to the main tank. Monitor the eggs closely for signs of fungus or contamination during their incubation period.
You would need at least a 150 gallon tank
You would need quite a large tank, as angelfish can grow HUGE. Fully developed angelfish can grow quite big, so if you want three angelfish, I would firstly recommend an extremely tall tank. They like tall tanks because of their tall figures. The tank would need to be at least fifty gallons, but that's the minimum. It's preferable if you have a bigger tank, to prevent stunted growth, early deaths, etc. My recommendation is a tall tank that is preferably more than fifty gallons.
I dont get it. Did your angelfish die?
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.
To maintain or gain leadership in an area, probably your tank.
Anything that's bigger than them. My angelfish is afraid of the light over the tank.
This is a common occurence. Angelfish do this a lot. She is just getting rid of an encumbrance. Two females will also get together and spawn much to the joy of their owner who then thinks he/she has a pair.
Angelfish are clever fish, from my experiences if you put your finger up top of the tank they will follow it.
take the eggs out and put them in another tank with water!!!!
It is not harmful. But if you want to clean up the algae in the tank you want to get a pleco. They are very peaceful fish and will not harm angelfish. I have a pleco and three angelfish in my 35 gallon tank right now and they get along great!
Terrapins lay their eggs on land.
