I'm back from my time away now, and keen to get back on the horse (turtle?) and would love your advice @Craig and @Aussiepride83 . I went and visited my local aquarium today, which has Macleays. I'm wary of going for another Macleay, but my first one came from this place (the second two didn't), and it was super healthy. My wife is not a fan of ELNs and I can't really do any bigger than a 4ft tank, so as I understand it, Macleays are really my only short neck option for a 4ft tank. They have two batches at the place - one about 4-5 months old, and one that is a year and a half old. The year and a half olds are all huge - like 10cm or larger. The 4-5 month old batch ranges from about 7cm down to about 3cm. There's one 5cm, and the rest are under 4cm. According to the guy that's down to how much they've been outcompeted for food given they're all fed in the tank at the same time. Given all this, I'm wondering: am I better off going for a larger one (say the 5cm), since it's obviously a bit more robust but perhaps less healthy in the long run because it's grown too fast, or am I better off going for a smaller one, which is less robust now but has a chance of being healthier in the long run? What things might I look for in terms of health signs? Either way I'd be keeping a daily written list of food, sun time, etc. Or am I better getting none of these and waiting for one to pop up on here? I know nothing is given (of all people, boy do I know) but I'm really asking for your best guess, based on your experience. Thanks.
