Thoughts on Bio Load
I have the Red Sea Max 250.
This gives me a surface area of about 800 inches and about 66 gallons of water (pre rock) At 1" per four gallons, I get 16.5 Inches of fish, with a max size of 3" per fish (I only am adding small fish), gives me only 5 small fish. At 48" of surface area per inch, I'm looking at the same number, about 16.6 Really changes the idea of adding a small school of anything, 3 chromis would be 60% of my tank load. Understanding that rules of thumb (love the history of that phrase) are only guidelines, I would like to hear some more experienced people's throughts and experience with greater bioloads.

Can't really go by inches. Assuming you have enough territories, enough rock, sufficient filtration and a committment to necessary husbandry, you can have more than 5 small fish.

I have about 70 lbs of Live Rock and the Skimmer that comes with the RSM 250. My skimmer seems fine, i think a lot of the kinks have been worked out of it.

Id say 6 to 8 nano fish.
If your thinking about a school of chromis, remember most people end up with 1. I had 3 in QT before it turned to none. They killed each other off. And this was before they had been in QT for 2 weeks. |

It's the Spotted Cardinalfish I'm thinking of schooling if it makes them happier. Otherwise I'd be happy with just one.

I'm not sure if my wife would like it if I hit her with a stick the width of my thumb! If you keep up with regular water changes, then I would think that you would be able to keep more than that. I run an RSM130D and have a pair of occellaris clowns and a fire goby and think that I am under stocked. I do regular water changes and my skimmer doesn't ever seem to pull anything out.

I really don't think you'll find many fish that really "school" like FW tetras, etc. do. SW fish may be "schooling" and still 8' apart. You aren't missing much (IMO) with skipping the chromis; they have a nasty habit of reducing their numbers to "1".

I would go with no more than 8 small fish for that size of tank. With LR and sand you will have much less than 66g of water. JMO.

Your math is correct, you get 16.5" of fish FULLY GROWN.
Chromies suck so pass on them. Do you think eventually you'll want to add some cool coral, if so, keep that in mind when making a stocking list. People always overstock and it turns into a fish masacre, don't be that guy. BTW, is the grounding probe installed? |

I have 5 small fish in a 29 biocube and all are doing fine. You should be able to put at least 10 in a 65.

Most tanks have the filtration to support far more than the size of the tank will allow. You have to worry more about how many fish you can put in before they get stressed from feeling cramped. Getting fish that fill different niches in the aquarium allows you to stock more without conflicts.
Cardinals do best in groups because they are social fish. They swim around more than I would've given them credit for before I got my trio. They are the only fish in my tank that follow me around the room religiously. They are much more active than I thought. |
