Spot Potential Issues Early

AquaLens's visual triage scanner flags potential anomalies on your fish. Get AI-generated observations and educational care suggestions to help guide conversations with your aquatic veterinarian.

AI-Powered Pathology & Precise Medicating

When the scanner flags a potential concern, the card highlights it with observations and educational suggestions. AquaLens helps you know what to look for, and exactly how much medication to use based on your exact water volume.

  • Anomaly Flagging — AI highlights visual signs that may indicate common conditions like Ich, fin damage, or fungal growth.
  • Medication Calculator — Calculate exact dosing amounts required for hundreds of commercial treatments directly against your true net water volume.
  • Monitor & Notify — Track active medication cycles in The Brain. Auto-reminders alert you when the next dose is due or when it's time to run carbon to clear the water.

* AquaLens is an educational tool and does not provide veterinary medical advice. Always consult a qualified aquatic veterinarian for diagnosis and treatment.

Morphology

Adults typically reach 5–7 cm in length. The body is laterally compressed with a vivid blue-violet iridescence overlaid with black vertical bars. A prominent dark spot sits on the flank, and the dorsal fin rays extend into elegant filaments. Females display a distinctive pinkish-red ventral coloration.

Diet

Omnivorous — feeds on small invertebrates, plant matter, and detritus in the wild. In captivity, thrives on high-quality micro pellets, frozen bloodworms, brine shrimp, daphnia, and occasional vegetable matter.

Ethology

A relatively calm dwarf cichlid that prefers the lower strata of the water column. Best kept in pairs or small groups. May display territorial aggression toward conspecifics during breeding season, but generally peaceful with other community species.

Etymology

Mikrogeophagus — "small earth eater"; ramirezi — named in honor of the ichthyologist Dr. Manuel Ramírez, who first collected the species from the Venezuelan llanos.

Hi, I'm Dave

By day, I run a small, highly specialized research company — engineering proteins, building biosensors, and leading a team of research scientists at the intersection of biotech and national security. Our work is funded by the DoD and DoE, spanning everything from critical mineral recovery to field-deployable biosensing platforms.

AquaLens was born out of my own frustration. Turns out, keeping lab notes isn't that different from keeping tank notes — weighing chemicals, controlling conditions, and obsessing over parameters. I wanted a better, smarter way to log tank data, track expenses, and monitor the overall health of my ecosystems. When I couldn't find an app that did exactly what I needed, I decided to build one myself.

Here's the funny part: AquaLens is actually the very first thing I have ever coded. Building this app has been a wild ride of late nights, endless Googling, and crossing my fingers that the server doesn't crash. It's a true solo passion project built by a hobbyist, for hobbyists.

Because it's just me behind the screen, I rely heavily on the community. If you find a bug, have an idea for a new feature, or just want to share a picture of your setup, I'd love to hear from you. Thanks for coming along for the ride!
