Huh, firemouths used to be one of the staple cichlids when I first got into the hobby. You could easily find them. Now that I think about it, I don't know if I've seen them at all in ages in any fish shop.
I've got a pair I bought last month as theyre an old favourite and I hadnt seen decent ones for years. Came home tonight to about a million babies and them chasing everthing in the tank
Wet Spot consistently has firemouths. Thorichthys are hard to find in general. Wet Spot seems to get more thorichthys species than anywhere else in general. TUIC every once in a while, but sell out pretty fast.
Not sure which “red hump” we are referring to. There could be 3 species of geo that are available in the hobby that are called “red humps”. G. Steidanchneri is the most common and easiest to find. Both places have them in stock often.
