#1: @OliveFish05 correctly identified Congo Tetra (Phenacogrammus interruptus)
#2: @JuiceBox52 identified the exact species of freshwater Sculpin, the Mottled Sculpin (Cottus bairdii), a dream fish of mine! @Circus is an honorable mention because she did get the type of fish.
#3, with a VERY impressive correct ID, @Caesar wins again, correctly identifying Gymnogeophagus Jaryi. If I may ask, how do you know this fish?
Harlequin rasbora edit: it's not a Harlequin rasbora; I'm not sure what it is, I took a second look and none of the members of Trigonostigma have those markings. So it's likely a tetra I'm unfamiliar with I'm guessing.
Yay! A contestant! I think I should’ve mentioned that the one that starts with an F is hard level. Let’s get more people! I want this to continue. It helps exercise ones fish ID skills. Even if you get it wrong, you improve from it. Let’s keep this going!
