nice! Did you get a look at the weird black arachnid that are always in their teeth? I am growing a group of Euchilichthys and finally figured out how to keep them long term.

#Alcolapia #latilabris in a spring at Lake #Natron. Dominant males feature lips that will never lie to you!

Always keep around an #Asterophysus #batrachus to eat your enemies, or at least try #rarefish #Amazon #Auchenipteridae

not giant, but giant headache.

Hemigrammus stictus, with the red not showing well.

When you want your male to have random red spots of the abdomen. Perfectly fine as a mate! #Myloplus #asterias #pacuorgy

Shaky owl post... but sometimes!

Reindeer Bot Flies Are Not Particularly Festive Adult reindeer bot flies look like harmless fluffy bees, but they're not really that cuddly.

Here is the article I wrote a while back that was described as "ruining Christmas for nearly everyone." My work here is done. 🪰🎄 www.wired.com/2015/12/rein...

Of course I have holiday themed images! Brazzaville - 2006

#lungfish, #Protopterus #annectens wild #albino form. Highly recommended as an emotional support fish for the holidays, travels well, eats just about anything and great listener.

I feel like you need to see Ophthalmotilapia boops from Lake Tanganyika also.
