Hmmm...cories
My tip is that the bigger the tank, less problems, not problem in water quality, problems in compatibility. Zebra danios were known as fin nippers but i have 8 of them in my 55 gallon cause my tank is rather "big" and they only keep it to themselves, for a 20 gallon tank you can't fit anything else other than the 8 zebra danios imo and less disease, better life for fish, longer living, etc
My advice is that only "Pygmy" cories should be kept in 10 gallon tanks. Some people will not agree but after what i have seen today...i saw a school of sterbai cories that were *drumroll* 8CM!! they were so huge!
Any tips/advices, fellow members?
