Surprisingly difficult to answer Gary I think it’s pretty damn simple- basically change a few litres of salt water every two weeks, top up a litre of fresh water daily and feed the tank
But, I think that’s fair to say it’s where it’s reached- the tanks on its 3rd transplant going up in size over the last 4 years- been the same routine, but it’s had its share of issues an learning curve.
Would recommend it as a fun hobby for anyone with a little biological sympathy and curiosity
