Young freshwater tropicals often need slightly higher dissolved oxygen than adults because growing fish have faster metabolism and gill surface area that scales differently with body mass; keeping oxygen a few mg/L higher during juvenile stages speeds growth and reduces deformities, especially in dense rearing or community setups. This is why gentle surface agitation or air-driven sponge filters are more important in tanks with lots of fry than in established adult-only displays. 🐟💨

We stock sponge filters, adjustable air stones, and juvenile-specific guides to help your youngsters breathe easy and grow straight.

Today is personal.

These weren’t just names on a wall or numbers in a headline.
They were brothers. Friends. Sons. Men with futures, families, laughs, stories, and people who loved them.

Some were taken in service to this country. Some lost battles long after the uniforms came off. And that’s something people don’t talk about enough.

The enemy isn’t always overseas.
Sometimes it’s the memories.
The silence.
The pain carried home.
The battles inside that nobody else can see.

This Memorial Day, I ask that we remember ALL of them.
Not just how they died — but how they lived.
The jokes they told. The loyalty they showed. The impact they left behind.

You are missed. You are remembered. And you will never be forgotten. 🇺🇸

Honoring the day with quiet tanks and loud gratitude. 🐟🇺🇸
Take a moment to remember the real heroes — we'll handle the fish pics later.
Stay safe, be kind, and maybe feed your community critters an extra flake. ✨

Big things are happening at Midwest Aquatics.
Today we met with Jefferson County Animal Control to discuss a potential partnership focused on improving care and placement options for surrendered, stray, and rescued aquatic animals, amphibians, and reptiles. After touring, discussing resources, and exploring future possibilities, they have agreed that once approved by management, Midwest Aquatics will assist with housing and rehabilitation efforts for these animals.
This is a huge step not only for us, but for the exotic and aquatic animal community as a whole. Many shelters simply do not have the specialized setups, equipment, or species-specific knowledge needed for fish, reptiles, and amphibians. Our goal is to help fill that gap and give these animals a better chance at proper care and rehoming.
We’re incredibly honored that local organizations are recognizing the quality of care, knowledge, and dedication we put into this every single day. Between our recent partnerships and outreach efforts, Midwest Aquatics is continuing to grow into something much bigger than just a fish store — we are building a true community resource for aquatic and exotic animal care in Missouri.
Thank you to everyone who continues to support us, shop with us, leave reviews, share our posts, and believe in what we’re building. Every bit of support helps make opportunities like this possible.
