If you are referring to the on-line calculator known as aq-advisor, I would simply suggest that they are are least as accurate as reading chicken entrails as oracles go.
I would stick at the 80% stocked that they currently state, thinking that further stocking is not needed. Best to you, rick
I would also increase the number cories, adding 2-4 more of the same species. Do not rely on Aqadvisor. There are far to many variables to consider when stocking a tank, it simply can not be done accurately with this tool. You are better off asking here, like you did. I assume your "Ruby Shark" is meant to be a Rainbow Shark? They should have a 4 foot long tank, as they grow to be 6 inches and need the swim space. Other than those 2 things, you could probably get away with adding another peacock gudgeon and call it finished.
I'm not 100% sure, but don't Siamese algae eaters need a school (also not sure if they're suitable)? Also the cories need a school of 6+. Then I would take out the rainbow/ruby shark like alink said and if you have to take out the SAEs, then you could have a larger school of tiger barbs (Since they're better in 10-15 and you have 9 which might be okay, but it's better safe than sorry).
Yes, some of my Siamese Algae Eaters do school, I have 6 of them in there. They also grow up to 6" so they're not really going to work. I would rehome the SAE and the Rainbow Shark, it will be too aggressive with this kind of setup.
Rainbow is an albino and at the moment 1.5 in when he gets big he will move to a 150gl that I rehome me fish to at a friends. The SAE idk what to do the only place I could bring him is back to petco because my friend doesn't have any either
