Recently picked up a little 30 litre tank in a charity shop for £5, and my aufishsm kicked in again after years of not owning a tank! This is it after about 2 months of work, what do you guys think? Any advice? (Yes I know it's probably overstocked but I have another tank on the way...) I personally think a nice bushy red plant in the filter corner would look great but I'm not sure what to go for.
