Deeply amazed by freshwater fish, cichlids in particular
Males of Pachypanchax patriciae showing beautiful red and blue coloration. Endemic to Madagascar northwest coast, the genus does best in cool temperatures as sex determination is temperature dependent

With a new Paretroplus species described in the damii group (Paretroplus risengi), it’s imperative to keep declining species from becoming altogether extinct #dtmf

The Shedd Aquarium in Chicago has undergone some dramatic upgrades to their freshwater and marine tanks. It is an even more amazing place to visit- obviously their Madagascar collection could be bigger 🥲

Years ago, 20 yrs, I had no clue these fish would be endangered or extinct. What does it mean to you to go through generational amnesia and forget what used to exist?

Few specimens of Paretroplus nourissati remain in captivity, in fact, no large institution in the world keeps the species. With a rapidly declining wild population, every spawn of this species is a gift

One of the most intriguing cichlids is this impressive Heterochromis multidens, males have an impressive nuchal hump. Iris coloration is also different between males and females

Pachypanchax species appear to be susceptible to lymphocystis infections (LCVD), an iridovirus that infects fish and amphibians. This Pachypanchax male developed what appears to be melanoma. Iridoviruses can infect melanophores causing a marked expression of pigmentation, only males are infected

When you are brightly colored while breeding and hunting fish-eatbirds are about, spawning in a cave is a survival skill. Paretroplus damii guarding a nest as a cave spawner 😍

It’s been a warm summer and setting new mops may help kick the breeding season in high gear for Pachypanchax patriciae

AOC: "On this point of tax on tips, as one of the only people in this body who has lived off of tips, I want to tell you a little bit about the scam ... the cap on that is $25,000 while you're jacking up taxes on people who make less than $50,000 across the US ... while kicking them off the ACA."

One of the few species of Malagasy cichlids of least concern when it comes to conservation, Ptychochromis grandidieri. Its ability to live in brackish water keeps this species safe from overfishing and exotic species introductions

Summer is in full swing in Texas, unfortunately that means no eggs or only male fry with high temperatures affecting reproduction in Pachypanchax sparksorum. So the new addition to the Fish Cantina is a small air conditioner 🤩

A beautiful pair of Paretroplus maculatus vying for spawning territory. Communication between specimens is critical to secure a pair and raise offspring. To this date, no scientific research has been done studying this particular species and its ability to sense and produce sound

Last minute spawn before lights out- excuse the dirty glass. Paretroplus nourissati rarely spawns in aquaria due to oversized conspecific aggression

Your occasional dose of cuteness. Kotsovato, Malagasy for wet rock, described the coloration of Paretroplus kieneri- now extremely imperiled in it’s native habitat 💔

One of the smallest and least known cichlid comes from India, Etroplus canarensis is a cute little jewel. This. Pair is guarding a fresh clutch of eggs- each is attached by a long relatively hard filament

Farewell to Dr Paul Loiselle who recently passed away leaving a vast legacy as a former director of New York aquarium, co-chair of IUCN Madagascar freshwater specialist, just to mention a couple that come to mind. Paul described multiple killies of the genus Pachypanchax and his work will live on
