Okay, so I'm thinking that Freedy's tank looks gross.
Not because the water is nasty, but rather because it's a bare-bottom tank with scuzzy looking fake plants in it. It just looks depressing. It has no light built in either, since it's a Kritter Keeper. So, I'm thinking about remodeling for him. :)
First of all, should I even bother redoing the 3.5 gallon tank, or should I just upgrade him to a 5 and mess with that? I'll probably catch a ton of flack for buying yet another tank (I have three in use and one 10gal in the basement), but I'd be willing to risk it if it would be good for him.
Second, if I was wanting to use low-light (easy) plants like java ferns, anacris and anubias barteri/nana to put in this tank, what kind of light would they need? Would they need any fertilizers? Feel free to suggest other plants as well.
Would having gravel in my tank make the wastes and ammonia build up faster, or would the plants help to prevent this?
His tank already has a filter and a heater, which I would keep, and also a fake rock that's not so bad.
