Bio-load question

What bio load would you consider the following in 70 gallon? 1 Gold Stipe Maroon,(1)Royal Gramma, (1) Jawfish, (1) Purple Firefish, (1) Wheeler's Watcman Goby High, Medium, or low? IF it matters flow is roughly 30x tank volume.

I think it is low. Everyone (here) seems to think bioloads are higher than me, though. They are all small fish. What it really comes down to is how well is your specific tank able to cope with it. The amount of LR , BB or DSB, Skimmer, volume of sump, types of filtration, husbandry activities, ETC... will all have an effect on what I would classify your bioloads at. Beyand the abilty of the tank to cope with it is how well your fish get along with eachother. If there is alot of aggression in the tank then that would be something to concider. I don't see any really aggressive fish in there, the clown could be concidered aggressive but, I wouldn't think you would have a problem with it.

I vote for low as well base on the adult leght of the fish, the firefish, royal gamma and the goby are relatibly small fish, the gold stripe marron, is this a clown fish? If so him and the jawfish are your biggest fish but they will not exced 6in.
Jason is correct about the equipment and lr and sand can change a bioload from low to high. You need to have a good skimmer and a good amount of live rock so the bioload is not too much.
Right now I am running my 20ga with no skimmer so my 2 fish would be a medium bioload, I know I cannot go more than a week with out a water change.
