Trigger Your Corys NOW!

It's October 30 and we have the first low pressure system in the Mid-Atlantic in MONTHS. Barometric pressure will be below 1000 millibars this afternoon. If you have adult Corydoradinae groups you've been trying to get going, try a large water change with cool water (take the tank down 5-10 degrees F). If you can get your hands on RO or distilled water, all the better. Do the water change any time between now and Halloween evening. Refresh your microworm cultures to get ready for fry... If you get fry they'll be big enough to sell by the spring auction. Let's go!

Inflatable Pools Market Making a Splash in the Global Leisure Industry

The Inflatable Pools Market has witnessed remarkable growth over recent years, driven by rising consumer interest in affordable and convenient home leisure solutions. As urban living spaces become smaller and families seek easy ways to relax without the expense of traditional swimming pools, inflatable pools have emerged as an attractive alternative. Their portability, cost-effectiveness, and ease of installation make them a popular choice for both residential and commercial applications.

One of the major factors fueling the Inflatable Pools Market growth is the increasing demand for outdoor recreation and family-oriented activities. The post-pandemic shift toward staycations and backyard entertainment has further accelerated market adoption. Additionally, manufacturers are focusing on innovation—developing durable materials, eco-friendly PVC alternatives, and creative designs that cater to all age groups.


The Inflatable Pools Market is also benefiting from e-commerce expansion. Online platforms such as Amazon and Walmart have made it easier for consumers to access a wide range of inflatable pool…

Amano Shrimp Breeding

The first of two Amano berried females finally released her eggs yesterday. I have now moved all the larvae to a marine tank with phytoplankton and tons of air flow to keep the water moving. Sorry, the video is a little washed out due to the phytoplankton, and it needs a light to attract the larvae to an area to capture a short clip. They are currently white to clear little specks, making it difficult for the camera to focus. The little specks to the left are all larvae.

Failed! Having a hard time getting the larvae to survive past day 2 or 3. I have a few left right now and did a complete clean out of the tank to rest it in the case there was something in the water. The conditions that changed right before the larvae died was a drop in salinity from me adding water to adjust the salinity back to 30% where it was close to 31% so about half a gallon of water and bubbler was set a little strong that night where there was a little more moisture from the bubbles outside the tank. Another thing that may have caused the crash might have been the sponge filter that is a course foam and the larvae can get caught there, but that is quite fast for the filter to do that to so many in such a short period of time.


The reset water now is set to 29% salinity with less phytoplankton to cloud up the water, bubbler set to halfway to show some flow of water around the whole 5 gallon tank, and no filter. If these remaining larvae do not survive the Amano females are already berried and the 1st of them should release her eggs in about 15 days.

Tetraselmis Phytoplankton culture

I have a culture of Tetraselmis Phytoplankton started for my Amano shrimp project. If anyone is interested, please let me know. I have actually used it to feed some brine shrimp that have made it to the marine tank setup for the Amano larve, the brine shrimp are thriving off of this phytoplankton.
