Tropical Fish Hobbyist are currently offering a free trial of their digital subscription! TFH are a fishkeeping magazine which is now available in print and also as a digital only version as well for those of us who are low on cash or wish to avoid increasing their carbon footprint. I subscribe to the magazine myself and have found the digital version to be as good (if not better!) quality then the printed option. I would recommend that everyone tries out the digital option for themselves and see how you get on!
