Mouthbrooding is a behaviour exhibited by some species of fishes, wherein they nurture their eggs in their mouth. The ocean can be harsh and predators, vicious. So mouthbrooding keeps predators at bay, allowing for the best care for their young.
Rhinogobius sp red lip belongs to a group of similar looking gobies found in China. From the different creeks some will have red lips, some will have yellow or orange and some running down the face. We currently have some very healthy red lip varieties. They are a dwarf specie that max size at 2”. Generally peaceful with other fish.

SHRIMP KEEPING… DOWN THE RABBIT HOLE. A discussion with Mr. Jacob Waters about freshwater aquarium SHRIMP!!
Jacob Waters’ Bio:
I started off in the saltwater world 20 years ago breeding clownfish and at one point had over 3000 cumulative gallons of saltwater aquariums up and running but got out of the hobby do to lack of time.
I got back into the hobby about 3 years ago when my 4 year old son saw a betta fish at the pet store and started to beg to have one as a pet. So we got one with a small self cleaning tank and about a month later after some research I found that it really needed a larger tank to thrive so picked up a small 2.5 gallon tank with a sponge filter and air pump.
The following week I found the club PVAS and went to my first meeting where I met Frank and ended up buying a bag of cherry shrimp and fell in love with the critters.
Fast forward to today and I now have over a dozen shrimp only tanks between home and work with many rare species and have myself specializing in the harder to keep Caridina. I am focusing on fancy tigers and Boa shrimp at the moment but also getting into the highly coveted Nanashi lines as well. I have made friends with some of the most well known breeders in the world and am doing all that I can to help grow the hobby of shrimp keeping.

These brine shrimp live in water that is at 12% salinity, nearly 4x saltier than the ocean.
𝐺𝑒𝑜𝑝ℎ𝑎𝑔𝑢𝑠 𝑠𝑝. "Redhead Tapajós" is finally described as a new species - 𝐺𝑒𝑜𝑝ℎ𝑎𝑔𝑢𝑠 𝑝𝑦𝑟𝑜𝑐𝑒𝑝ℎ𝑎𝑙𝑢𝑠 (thank you Logan Holfelder). Hailing from the Tapajós River basin, Brazil, this species of eartheater cichlid is popular in the hobby and was first imported in 1991 by German aquarists Christoph Seidel and Rainer Harnoss.

(2022), A new species of 𝐺𝑒𝑜𝑝ℎ𝑎𝑔𝑢𝑠 (Teleostei: Cichlidae): naming a cichlid species widely known in the Aquarium hobby as “𝐺𝑒𝑜𝑝ℎ𝑎𝑔𝑢𝑠 𝑠𝑝. Tapajos Red head”. J Fish Biol. Accepted Author Manuscript. https://doi.org/10.1111/jfb.15207
𝗔𝗯𝘀𝘁𝗿𝗮𝗰𝘁
A new species of 𝐺𝑒𝑜𝑝ℎ𝑎𝑔𝑢𝑠 𝑠𝑒𝑛𝑠𝑢 𝑠𝑡𝑟𝑖𝑐𝑡𝑜 is described from the Tapajos River basin, Brazil, elevating the number of species of the genus to 21.
The new species is of commercial importance and is known in the aquarist trade as 𝐺𝑒𝑜𝑝ℎ𝑎𝑔𝑢𝑠 “red head”. The new species is diagnosed using an integrative approach, based on mitochondrial DNA analysis along with morphological evidence.
The new species is distinguished from all congeners by the absence of markings on head, the bar pattern composed by nine vertical bars on flanks, and the presence of distinct longitudinal bands in the caudal fin.
Additionally, it shows a genetic distance of at least 2.0% in cytochrome-b gene sequences from its closest congeners. Molecular analysis including most genera of Cichlidae from South America corroborates that the new species belongs to the group of 𝐺𝑒𝑜𝑝ℎ𝑎𝑔𝑢𝑠 𝑠𝑒𝑛𝑠𝑢 𝑠𝑡𝑟𝑖𝑐𝑡𝑜.
𝗘𝘁𝘆𝗺𝗼𝗹𝗼𝗴𝘆
The name 𝑝𝑦𝑟𝑜𝑐𝑒𝑝ℎ𝑎𝑙𝑢𝑠 combines the Ancient Greek 𝑝𝑢𝑟𝑟ℎ𝑜𝑠 meaning "flame-coloured" or "red" and -𝑘𝑒𝑝ℎ𝑎𝑙𝑜𝑠 meaning "-headed".

While aquascaping has been around a very long time, it’s during the last couple of years that the art of underwater gardening has really taken off. By working in a small space, namely a fish tank, it’s a great way to add greenery to your life without needing a backyard, or even a courtyard.

The Potomac Valley Aquarium Society was founded in 1960 for the purpose of furthering the aquarium hobby by the dissemination of information and advice, and the promotion of good fellowship among the members by organized activities and competitions.
Our club meets every month the first Saturday of the month except for the Spring and Fall All-Day Auctions which fall on Sunday. Sometimes the dates, like the July Bowl Show, are pushed to avoid a holiday so always check the Program.
Meetings are free and open to the public. People who attend more than one or two meetings per year are asked to join the club. The annual membership fee for individuals is only $20/year and helps us pay for the meeting room.
