I've done a little research on the best heaters but people's product reviews always psych me out a bit. What do you guys think would be the best heater for a 2-gallon tank?
I've also noticed that his tank is getting a little cloudy already... I'd guess the combined effect of it being a used tank (on a tight college budget here, haha) and possibly new and dusty gravel, but I'm not entirely sure. I'll try changing the water and cleaning everything out in a couple of days, because I don't want to stress him out by moving everything around again a day after his arrival.
For the plant, I did a little digging around on aquarium plant sites and the closest matches appearance-wise seem to be echinodorus tenellus (chain sword) or possibly some type of vallisneria.
Today I went out and got him a mug for a cave! I of course checked on what glaze was used to make sure it was safe, no lead or anything. He's been checking it out and hiding inside already. :)
