CE is "right on".

I did not participate in the poll as, IMHO, no option was applicable.

If anything the "general rule of thumb" should be modified to Volume of Fish/Volume of Water but

as Ce indicated even this "general rule of thumb" would very quickly break down for large fish.


One other item:

Fish (just as humans) require a given amount of protein.

Typically animal matter is higher in protein than plant matter.

Fish which are herbivores produce significantly more waste than carnivores or omnivores and hence would require a smaller ratio as well as increased biological filtration.

[... I would add that scalare angels need at least 18 inches height of the tank whereas altums will require 24 inches or more. ...

Blue:

In West Texas if 3 is good, 5 is better but therefore I always get 7.

Hence the 30" tall tank which I purchased to raise angels (or discus: which Alex has "trashcanned" for a community tank) to full maturity.

Same with the Yoyo's, Cories and SAE's: if 3 are recommended, 5 are preferred I have 7!
