I need to focus my research on what fish are compatible with what because I'm falling in love with so many different fish but I know just like freshwater not everybody gets along. I definitely want a kano angel I fell in love with them the first time I saw their pattern and possibly a flame angel, clown fish, snowflake eel and whatever else I can find that will work together in a community.
More research is definitely a good idea before starting to throw fish together.
A Kano angel? I am not sure what fish you are referring to.
I wouldn't keep another dwarf angel with a flame in a tank that size. Many people will probably say it's ok, but it is risky.
The snowflake is a no go in the 55 gallon unless you are going to keep it by itself. Just gets too big and will eat/try to eat anything you could put with it in a 55.
Keep throwing your ideas on here and we will help you out with what works.
