I have five adult Chindongo (Pseudotropheus) saulosi, 4 males 1 female. The colony has collapsed but they might make a nice, free addition to an mbuna community tank. Can bring tomorrow or make other arrangements.

Hi Everyone, The July Bowl Show & Indoor Picnic will be held on July 13 at Green Acres. We all love a good feast. Please share what dish you will be bringing here so others can plan what to bring and we can fill menu holes and avoid duplicates. Of course, there can never be too many deviled eggs, right? Please remember to bring serving implements if need for your dish.

Wanna keep the best cichlid from Lake Malawi? C. saulosi are a relatively small mouthbrooding mbuna (rockfish inthe local languages). What makes them great is that they're among a small group of cichlids where the males and females are very colorful, but completely different from each other. Males are gorgeous iridescent blue with black bars while females are bright yellow-orange. A small group of six or so can be kept in a 40-50-gallon aquarium and they look great as a species tank. We keep them in a 65-gallon tank. C. saulosi are easily bred and raised. Mouthbrooding females can be separated into a nursery tank and then removed once they release the fry, or can be stripped and the eggs raised in an egg tumbler. Fry are large enough to eat crushed flake foods and micro-sized pellets. We have a bunch available including 2-inch or so where the males are starting the change color, and some around an inch that will grow quickly. PM me if you are interested in giving them a shot!

Do you ever find fish in weird places? Like they migrate between tanks when you're not looking? This Ancistrus sp. L509 was a juvie from a group that I moved out back at CatCon 2022 (more than a year!). He just turned up in our C. saulosi tank. No idea how he got there.
