you could use fish if you use the Diana Walstad methosd in which the plants are the filters, removing any NH3 therefore skipping out some of the cycling process, everything is natural so no artificial ferts, just nutrients from fish waste & food. a soil substrate is used which has high CEC
Well some of you will be happy to know (though some will not be bothered still) that i picked up a hagen elite mini filter and found a place for the tank where there is a plug socket just in reach. I'll be going with a betta i imagine. Was interesting to hear your views on it though.
Thanks again people.
the question to ask...
if you have so little facilities for this tiny tank.... why bother...
bin it. lol
