Hi all. I have had a 20 gal nano tank for a while now and have also added a new 32 gal bio cube that has been up and running for years with the previous owner and about a month since I moved it to my apartment. (I kept filter material live rock etc.) tank parameters are all excellent (haven’t checked calcium/alkalinity though). And it has been very stable for weeks. I am planning what what fish I will add to this tank and was hoping I might add a juvenile tang. Before everyone attacks me for the idea of a tang in a tank that size I do plan to rehome the tang when it outgrows the tank. My questions are these: can a juvenile tang be housed in my tank? is my tank mature enough for a tang? what species is recommended? what species grows slowest and needs the least swimming room so I can house it the longest? what tangs are less aggressive? what tangs are best at controlling algae? is my tank mature enough to add fish like this/when will it be ready? what size is too big/when to rehome tang? i hope some experienced reefers can weigh in. Ting into account all those questions what tangs would you recommend if at all? I want something that I can buy small, will stay small for longer, is able to grow largest before needing a new home, and is a decent community fish with other semi aggressive species (damsels wrasses dwarf angels hawk fishes etc.)? thanks to anyone who takes the time to read all that and can offer advice. I really appreciate it.

So I have dino's and after doing extensive reading I have learned that adding biodiversity to the tank and nutrients is the way to go. My plan is adding microbacter7, phyto, and copepods. Most get their pods from algae barn but being in canada that's not possible. I have limited choices apparently. I have found 2 sources so far. These are what I have been able to find so far. https://copepods.ca/collections/packs/products/copepods-and-rotifers-live-concentrated-zooplankton-blend-16-oz Or https://sustainablemarinecanada.ca/products/reef-nutrition-tigger-pods Would either option work?
