There are actually 3 spawning Viscous Clots in Bibiki Bay.
One is however a "shared/lottery spawn", with another mob on the beach at H-7 where the Manaclipper docks. (If you check Bibiki Bay - Purgonorgo Isle on FFXIclopedia, you actually see this 3rd clot on the screenshot example)
The traveling time (+ killing time) between the two -permanent- Viscous Clots around H-10 and I-9 is however enough to just dash back and forth, between those two, since the 5 minute respawn time won't have you waiting too long.
With THF as subjob (Treasure Hunter I) I experienced the drop rate as approx. 1 Clot Plasma /4 hours, so the camp is not exactly a "goldmine", as there are faster ways to earn similar amounts of gil. I'd only recommend farming these, if you're either crafting with them, --or if you happen to be in the area, with nothing better to do for a while. (eg. waiting between re-pops for the Uragnite NM, Shen)
Other than dropping in Limbus, you can farm these from Viscous Clots in Bibiki Bay - Purgonorgo Isle. There are only 2 clots that spawn 1 at I-9 and 1 at H-10/11. Very low drop rate. Also on the Manaclipper a Clot will spawn from time to time and it also drops plasma.
"And let the over stock begin figure this happen if i started farming these for profit that people would notice =/"
Has 0 to do with people jumping on your farming band wagon, and has everything to do with the fact that these aren't all that rare of a reward from chests in Abyssea.
