this is the hob on a 5 gallon I am setting up - probably not supposed to do this but I like to experiment and it looks healthy so far I have also done a terrarium ? not quite sure of the correct term but we have such a great source of plant life where I live I feel compelled to try different things and 1 more - that's enough for now , dont want to bore you !! Thanks for looking I love this website/forum as it covers the huge area not really included in planted tank forums . Thank you to the moderator and creator of this site.
