AI is going to kill animals. 12.12.2025

The advice that various AI platforms are pumping out is dangerously wrong, this is fine if it's just a random fact, but now when people are using this, and pushing it to treat animals, Fish especially. 

Cheap fish 10.12.2025

Deformed, diseased, and cheap. So many of the fish that are being sold, shouldn't be available at all. Let's stop thinking of this as a cheap hobby and start looking to pay more for our pets.

Ballons. Can we just not, please 21.11.2025

This rant is brought to you by frustration, so much that my darling assistance dog told me my blood pressure was off part way through. Listen to the rant. You'll understand.   The dog world has brought out a set of standards for dog breeding, and in this rant about that, I lay outr some standards we also should use. 

Ways Your Fish Tank Can Kill You 19.11.2025

There seems to be a multitude of ways that your fish tank can if not kill you, at least do you a serious mischeif.   Let's have a quick run down of the main dangers and how you can avoid some of them. Please forgive me having a cold and sounding more stuffy than normally. Normal service should resume soon enough.  You can find out more info at  www.tropicalfishkeeping.co.uk  

I Love Fishkeeping 14.11.2025

They're coming for our hobby again 12.11.2025

The Don't Pet Me campaign has come out and seems to be saying that the fishkeeping hobby should be subjected to a positive list, and heavily restricted. It seems that we aren't capable of keeping fish without significant welfare issues. Join me for my thoughts on these ridiculous ideas, and even though many might think this is targeted at primates, and big cats, fish keeping is the area really at...

It's not Swimbladder 07.11.2025

Livebearers are fascinating fish, from the humble Guppy that graces so many of our tanks, through to less well known species, but there's a lot more than meets the eye. Come and join me as I dive into the world of livebearers.   

Problem Genes, should we care? 31.10.2025

Welcome back to the irregularly scheduled rants, this is a topic that gets me so angry, and I can see the issues that are facing the industry. But we as keepers can make choices, and even if that isn't the same choice that others make it will still matter to the fish you keep. 

What are your parameters part 3 the final part 29.10.2025

Welcome back to the final part of the question, what are your parameters. This time we are looking at hardness and phosphates, and then that is it for analytical chemistry for a while.    So dive in and learn a little more. I'm aware we've done hardness in another episode, but it never hurts to revisit this topic. 

What are your parameters part 2 23.10.2025

Continuing looking at the water tests that should be a regular part of your fish keeping, looking at nitrates and pH. For beginners and more experienced aquarist alike.    Nitrates are so often miunderstood, they're seen as being completely safe, but in fact they are deadly at higher concentrations. 

What are your parameters-part 1 22.10.2025

What are your parameters is a question I ask far too often. Most issues in fish keeping can be traced back to issues with our water, so when trying to help I will ask that question.  But what do I mean, what are I refering to when I ask that question? What is ammonia and why is it an issue, why do we want to know. Where does ammonia and nitrite come from, and what harm do they cause?   This is for...

Are 90% of Aquarium Fish Wild Caught? 15.10.2025

According to a recent article 90% of aquarium fish are wild caught, and that's destroying the ocean. Is this even close to the truth? And are wild caught fish even an issue that the aquarists need to be concerned about?  The first episode back after an unplanned break Ruth explores something that she's passionate about. How aquarists can use their hobby as a real conservation tool.

Species Spotlight- Guppies 31.05.2023

One of my favourite little fish, the guppy is a great addition to the right set up, but all too often they're not kept right, the adults are cheaply bought from the pet store, and no selection on the fry that are born. 

Getting Started With Plants 29.05.2023

Plants can be an amazing part of any tank, and the hobby of fish keeping, but it can be expensive and intimidating to get into. Here's a way of dipping a toe in the water, and hopefully something that's nice and easy.
