It's been interesting watching the guy opposite me learn the ropes of fish keeping. One thing I've been reminded on is that there is an incredible amount to learn.
First lesson on cycling was reduced to ammonia 'bad' and nitrates = water change. Entire discussions we have here on exactly what level of nitrates was bad (if any) was out the window. Ammonia vs ph got a real blank look. Nice to know it's not just me that has bad chemistry
Second one was on feeding fancy goldfish and issues. This time he had googled some good answers and just needed a bit more. Got two useful tips across. Still nagging on a water test kit but he does have a filter now so great progress.
Is the tank too small - yep, it will be. I'm not a huge fan of small tanks as I find them limiting although I recognise many people make them work well. But baby steps, baby steps - the interest is there, he's learning and the fish are going ok.
