Okay, let’s answer the goldfish questions. 😂
Last year I shared why we keep goldfish in our cattle tanks and apparently I opened Pandora’s fish tank.
🐟 Why are they in there?
A friend with a giant koi pond needed to rehome about a dozen small goldfish and koi and asked if our boys wanted them. Obviously, they did. 😂 So into the stock tanks they went!
🐟 Do the cows ever eat them?
No!! They’ve lived together quite peacefully for years.
🐟 What about fish waste?
We clean the tanks regularly, but honestly, the cows are much dirtier than the fish. 😂 Stock tanks collect dust, debris, whatever the cows backwash into them, and algae can grow quickly in the summer.
🐟 Do you still clean the tanks?
Yep! Goldfish are not tiny aquatic housekeepers. Unfortunately. 😂
🐟 How do they survive winter?
Our tanks can’t be allowed to freeze anyway because the cows need access to water 24/7. A single cow can drink a LOT of water each day, and we have four cattle using these tanks.
We top them off daily year-round. If ice forms, I break it several times a day, and during an Arctic blast I’ll add a drop-in tank heater.
🐟 Are the fish safe for the cows?
Yep. Cattle with access to ponds, streams and other natural water sources have been drinking water that contains fish and other aquatic life forever. Our cows remain deeply unconcerned about their drinking buddies. 😂
