As someone who has bred guppies for the last few years, I’ve honestly started questioning why they’re so often called a beginner fish 🤷♀️
I totally get why people love them — they’re cute, colourful, busy little fish with loads of personality, and honestly, they’re one of my personal favourites too 🤍
But in my experience, guppies have actually been one of the more sensitive and higher-maintenance species I’ve worked with.
A big reason is water chemistry.
Guppies do best in harder, mineral-rich water, and here where I live in Cape Town, my tap water tests at only around 1° GH — which is very soft for guppies long term.
So I personally supplement minerals to push that up to around 5°+GH, but realistically… I don’t see most beginners rushing out to buy test kits, monitor hardness, and buy products to raise it.
A lot of YouTube advice makes guppies sound super simple, but that doesn’t always translate well to the water in my area.
They also often suffer from internal parasites and need repeated deworming treatment, which is not always something beginners are familiar with or prepared for.
I’ve definitely got more to say on this topic… so let’s just call this part 1 😅
