Be warned, these things are escape artists. Mine climbed up the wire for the heater and escaped. Found him two rooms later, unfortunately dead.
We had him a grand total of one night.
Ooh, I bet the dogs would get a kick out of that. Dolly likes little things that scuttle around on the floor that she can squish and root and slobber.
You could try an African dwarf frog, like MacTech said. I had one in a 5-gallon tank for a long time. He lived to be 10 years old, which is older than I was told he’d get, so I guess he was pretty happy. He was easy to take care of - no heater is required for them, just room temperature water is fine. Pretty much all I’d do is change the filter when it got dirty and clean the tank about every 2-3 weeks. I fed him ‘frog chow’ - a pre-made food - one or two little teeny chunks a day.
You would need a lid on the tank, though, as they can (and will) jump out. You also need marbles or rocks on the bottom of the tank rather than gravel, as they tend to try to eat anything that’s not bigger than their head. I used plastic plants since my frog would definitely have tried to eat real ones.
Mine would sing late at night, so if you are a night owl you’d get to enjoy that.
:snort:
It’s too bad they weren’t here, the little guy might have been found sooner. As it was I was so pissed that good money went to waste in 24 hours.
This dredges up sad memories
Maybe you guys are thinking about a different sort of Angelfish. Ours lasted a couple of years and was about the size of a Canadian two dollar piece. We also had a little catish, possibly a Danio, that outlasted all the guppies and the Angel. He ended up all by himself after something went through and killed off all he guppies. By then, we’d gone to a ten gallon and regularly sold off the excess guppies to our local petstore. I don’t know what happened. I guess I was about ten or so at the time.
I’ve got a crayish story too. I had a little local guy many years ago. He was about two inches long and since he was short an arm, we called him Capt. Hook. He lived in a little tank in our livingroom quite happily. I only kept a few inches of water in there and built it up with stones to mimic the stream I’d found him in. I even kept him in his “home” water. Well, one day the mother-in-law came over and took offence at the fly situation. She ended up accidentally Raiding poor old Cappy. :smack: 
Of course she hadn’t meant to, but she never thought of covering the tank. (Nowadays of course I wouldn’t get a wild one or I’d keep it at work where we’re permitted for indiginous species.)
Have you considered newts? Some of them are very aquatic and only need a floating platorm for the odd time they want to come out of the water. The little red or fire belly newts are usually quite inexpensive. The Spanish Rib Newts we have at work are pretty well totally aquatic. They have an interesting way of defending themselves too. If a predator grabs 'em, they stick the ends of their ribs through their skin and the predator gets what amounts to a mouthfull of fishbones. :eek:
After browsing forever at the fish shop today, I ended up going fairly simple and inexpensive.
I got two small blue paradise gouramis, each about two inches. They’re big (for this tank), active, and from what I can tell, pretty much indestructible.
I also got three tiny little Pakistani loaches. They’re far smaller than most loaches, and they’re very pretty and fun to watch. They love the plants.
Everyone is doing great so far. I still have the two little danios in there, which may prove to be a bit much; I’m going to test my water daily for a while and up my changes, and move the danios to my big tank if it is going crappy in a hurry. I might add some moss or other “ground cover”-type plants, but for right now I’m happy with this tank.
