This week’s #sundayfishsketch prompt was spooky fish or fish w/spooky names. I started down a toadfish rabbit hole b/c they always look menacing. Discovered a new group to me. The plunderfish with their odd little chin barbels. Denizens of the cold waters of the southern oceans around Antarctica.

Forgot to cross post, so it’s a dah behind. Better late than never
Although colorful enough to be a REEF fish, I painted it for the RIFT prompt of #sciartseptember and this week’s #sundayfishsketch. Haplochromis obliquidens, a cichlid from Lake Victoria and the rift system of East Africa

Haven’t kept up with #sciartseptember very well. Here’s a plains minnow for the #vanishing prompt from earlier in the week. Once, one of the most common minnows in the sandy drainages of the Kansas and Arkansas rivers, flow regime changes greatly reduced their numbers #sundayfishsketch
