Just an additional question to setting the tank up:Cool, that's why I asked re: plants - that will help with stocking levels too. I think you'll be able to do the Congos no problem but I respect your decision to start small, most don't.
Please post a proper thread when you get the Polys and Ctenos moved in!
Have you guys all got sand tanks or did you stick with finer gravel (2-3mm)? I have just used some fine gravel/sand in my malawi tank but obviously having plants in there wasn't needed... Do plants work fine in sand? And is there any sand you could recommend?
