How many fish in a 150g tank? And how many angel fish?

[ScotJ]

I know there are alot of options, and it'll vary based on size of the fish and such; but is there a general rule? Like 1 fish per 1.5g or something?

Also - I have one angel fish right now (not sure which type, he is brownish in color with dark yellow vertical stripes). I think they are awesome fish, and want to add a few more other angels; would it be posisble to have 4-5 in the same tank?

depends on size of fish. i have no clue about sw but i know gen speaking a 3-4 inch fish is going to be different then a 8-10 inch fish. stocking will depend on what fish you want.

I try not to get involved in the inch rule. It really involves size and if they are a messy eater or not. Messy eaters like eels and lionfish will allow less in your tank while community fish like tangs and other peaceful fish will allow more. I know that`s not the answer you wanted but I think it`s the right answer. IMO 6 or 7 inches of tangs (herbivores) is not equal to 6 or 7 inches of lionfish. What type of filtration are you using? That makes a difference also.
