ideas for a small tank...

A couple of Bumblebee Gobies would be cool in a small, 5 gal brackish tank. They prefer live food like brineshrimp and livebearer fry. I'm sure they would take frozen food as well, though they don't usually go after flake foods.
 
more choices

Another fish i would recommend is the Paradise fish, Macropodus opercularis . I have one here at work in a 2.5 gallon tank. He is fiesty and is the fav of everyone who comes here.
In my six gallon here at work, i have 6 Zebra Danios and 1 skunk botia Botia morleti . Doing plenty of water changes and plants and everyone is doing fine. :D
 
wow, less than 10 hours and i have 10 new posts...im thrilled! I have considered the blue ram quite a bit, but considering they would thrive more in a larger tank, i will leave it to someone who can provide it more room (aka, maybe when i stock my empty 29 later this year...). I really want a live planted tank with fish that would work with that. What about dwarf puffers? anyone have luck with them? i have heard that they are the only species of puffer that doesnt require a brackish environment...but i dont know much else about them. those bumblebee gobies were cool, but i know nothing about keeping a brackish tank, zip actually! Thanks guys, and im still watching for new ideas too, the more i get, the easier it will be for me to decide so THANKS!
 
Dwarves are not the only FW puffer, but they are quite popular. While their small size would make them ideal, I now advise against keeping them in a small system because it is really hard to provide enough adequate nutrition for them. Live snails are the best food for them, and in small tanks, they will hunt and eat every last snail. I had mine in a 5 for a while, and then moved them to the 40--huge improvement. Even in the 40, I end up supplementing them with snails (grown in another small tank).

A single dwarf gouramie and some dwarf cory cats would do well in there, or a trio licorice gouramie.
 
how many snails can a tiny puffer eat though? Like i have a little gallon aquarium i could raise the snails in and put in like 10 a week...how many do you think 3 could eat in a weeks time?
 
Those tiny puffers will go through snails at an unbelievable rate. When I had mine in the 5 gallon tank, I would put in 40-50 medium sized pond snails each Friday, and they ran through them before Wednesday of the next week. I didn't raise these, I scoured the LFS tanks for them.

Once they get older, they'll start taking prepared foods, so the snails are primarily to keep their beaks in good condition. However--I will never put the dwarves in a small tank again. I thought I was doing really good with mine, until I moved them to the larger tank, and within about 2 weeks they had all grown significantly and had better color.
 
You could go with some white cloud moutain minnows. They may not be as interesting as a puffer, but they are hardy and easy to take care of.

I just decided this morning that i no longer liked the ugliness and crappy filtration of my 5g tank, so i went and bought a 7g minibow with a mini penguin filter (at 100 gph!). I dont really think that gives me any different options, but maybe it will allow me to squeeze in one or two more fish??
 
Sorry to jump in, but can I just go back to the bit about rams please? I have always thought 5gal too small for rams, but has anyone kept them successfully in a 5gal? If so I will certainly consider them myself, as I have a 5gal (with guppies in at the moment just to keep it going) which I was going to keep Endlers in…but I’ll be damned if I can find any! And if so, is it a particular type of ram? They have some lovely ones at my LFS but they are just labelled as ‘rams’, I have no idea what variety they are.

Again Im very sorry to jump in, I don’t do it as a rule….but thanks if anyone can help.
Thom.
 
I would agree with most of the fish listed, especially the white Cloud minnows, gourami, and Bettas. When one thinks of Bettas they think of a fish that doesn't do anything, just floats with big fins drapped over it, but when given room they are active and have a lot of personality. I would also suggest zebra danios or other danios, another active schooling fish.
