What I'm really wondering is this: let's say that my tank hold 66g of water after displacement by the substrate and rocks, etc. Now:
1. If the tank by usual rules can support 66 inches of fish, but I have 10 Amano shrimp in the tank, does that mean that I should only add 56 inches of fish to go with the shrimp?
2. If shrimp do not have 1:1 bioload ratio to the fish, what is that ratio - smaller, larger?
It's just a nitpicky, curious point I'm trying to figure out. I don't expect that I am going to play with the inches per gallon threshold that closely to really make a difference.
BTW, because of the plant cover in my tank, I cannot tell whether all of my shrimp are surviving. I can count maybe 2-3 at a time. I am assuming that all the others are in there but hidden among the plants and other nooks and crannies.
