I had no idea when I created this completely unique XL Floating habitat for my beloved Blood Parrot #cichlid #fish that they would both move in together! It is hilarious how inseparable they are; I call them the Mean Girls because of the way they will gang up and pester other fish. Better than tv! Find me on Ebay!! https://www.ebay.com/usr/crystal_fish_caves #fedigiftshop #shophandmade

Warning: my #BloodParrot #Cichlid fish really hate the gravel vacuum and are pretty foul mouthed about it, but its hilarious! #fishofmastodon #comedy #joke #pets #aquarium #tropicalfish

Success!! My XL Floating #Cichlid tubes are a hit! They started chasing each other through it almost immediately adding a whole new level for the #fish to explore. Want one? Find me on Ebay! https://www.ebay.com/usr/crystal_fish_caves #aquarium #fishofmastodon #handmade #shophandmade #fedigiftshop

Difference in body size (or sexual #dimorphism) between males and females is common across the #animal kingdom. One of the most extreme examples of sexual dimorphism is found in the #cichlid #fish species Lamprologous callipterus from Lake #Tanganyika in East Africa

New pre-print alert 🚨 morphological variation between cichlid species manifests during early embryonic development 🐠🥚 or "show me a #cichlid embryo and I will tell you who they are". see 🧵below:

@evodevo_papers This #cichlid #speciation paper is cool. I'd love to see a video version demonstrating differences in the three species' development, in three side by side boxes. One suspects the questions asked will ultimately need to be broken into two stages: (a) "initial" morphological changes that support reproductive isolation of a subspecies, and (b) subsequent morphological changes.

Few months ago, we took #cichlid embryology to the next level... and now our results are published!🎉 Go to http://doi.org/10.1111/ede.12429 and (re-)learn how divergence in embryonic development between species contributes to morphological diversity 🐠🥚

Success! My prototype of an xtra large floating #cichlid caves is an instant success, so much so both bloodparrots moved in at once! How freaking adorable is that?? https://www.ebay.com/usr/crystal_fish_caves #aquarium #fish #handmade #crafts

This PhD project will explore the role of visual systems as magic traits, using haplochromine cichlid fishes as a model system.

We concluded that C. virginalis is deeper bodied and males have a distinctive breeding dress with a yellow upper surface & yellow dorsal fin, separated by a narrow black band at the base of the fin (c), while C. mloto is slimmer with males showing yellow only the anterior part of the upper surface (if at all) and having a wider black base to the fin that gets gradually broader posteriorly (g,h). Females of both are silvery (d) but can be distinguished by body shape. #cichlid
