Is your aquarium overstocked? Find out in 60 seconds
Ever bought a beautiful fish, only to find it doesn't get along with your others? Or watched your tank get cloudier and cloudier as you add "just one more"?
We've all been there.
That's why we've created something that should have existed years ago: a fish stocking calculator that actually works.
Here's what makes it different:
✅ Smart compatibility warnings – Not just "aggressive" or "peaceful". You get specifics like:
"Tiger Barbs will nip the fins of your male Betta"
"Your Oscar will eat fish under 3 inches"
"Only ONE male Betta allowed per tank"
✅ Real stocking calculations – Choose from three different rules:
Very Safe (0.56 cm/L) for pristine water quality
Balanced (0.75 cm/L) for a good compromise
Traditional (1.0 cm/L) if you have excellent filtration
✅ 135+ fish species – From Neon Tetras to Oscars, with accurate sizes and requirements
✅ Works YOUR way – Litres or gallons (UK & US), Celsius or Fahrenheit
Best of all? It's completely FREE.
No signup. No credit card. Just helpful information that saves you money and keeps your fish healthy.
