I have my betta in an unfiltered 21 litre (5.5 gal) tank. I do my best to monitor the ammonia levels, and I do partial/full water changes when necessary. I haven't yet decided if I want to get a filter yet, as I really have no problems doing water changes - It's not really a bother at the moment.
I'm just curious as to whether you guys think it wise to every now and then put a leaf, or two, in the aquarium, just to float around. Not for any reason in particular, but I think it would provide Marcel with some nice shade and comfort. I'm only asking because I'm curious what effects, if any, the leaves will have on his tank's contents, ie. waste, ammonia, pH.
These will probably just be either dead or green leaves that I find in my backyard. Nothing too dilapidated, of course. I will maybe put in one or two at a time, depending on the size of the leaf/leaves.
Could I just leave them in there for a few days, take them out, and then do an ammonia check?
Thanks a lot. I realise this isn't the most pressing quandary, and it's not really essential for Marcel's wellbeing, but I thought it might be a neat idea.
