i have a spare 16ins by 8ins by ins tank, which i know is very small, but i wondered if you lot had any ideas on what i could put in it. i have a choice of substrates for it: either peat, sand or gravel, a choice of filters: undergravel, sponge or box, a variety of plants i can nick from my other tanks, and others i can order in. i was just wondering if you lot had any ideas on how i should set it up, and what fish i should keep in it. other decor available could include rocks or wood, any ideas?
