Not a lot you can do with a 10G in terms of a variety of fish. Guppies, as you mentioned, are very colorful, and if you stick to males, you won't have an issue with breeding. Guppy males are where the color is anyway. Guppies and most other live-bearers prefer hard water with a fairly base (high) PH.
There are several small, colorful tetras on the market that would do fine in a small tank. Just try to get them in small groups, as tetras are a gregarious fish. (Please stay away from glofish tetras though. Modifying them so they glow is a cruel practice)
If you want a variety of color, you can put 1 male betta in with several females (3-4 max). They would likely breed for you as easily as guppies, but the betta breeding process is more fun to watch.
All of these fish need heated water. If you want an unheated tank, you could go with a small group of white clouds, or probably a single fancy gold fish. A gold fish probably won't leave snails alone though.
So its OKAY to have multiple bettas? If I had one male and say one female they would have no chance of fightng? Do you think the male would pressure the female for mating and such? Also, what kind of tank do bettas like? You often see them in tiny plant jars, but do they like tunnels and hidingplants? Also I've read about bettas nipping at snails and dwarf frogs.. true or un true? If thy did mate, does the male eat the fry like guppies? If a male was produced and grew up would the dad fight with it also? Sorry for all the questions, just looking for a reliable source..
First question: Don't go for multiple bettas in the same tank. I've read where people say okay to have multiple bettas, but I've heard its really hard to do and can only be done with females. Wouldn't suggest it because you need a larger tank then ten gallons, and if this is your first tank you probably lack necessary experience. Keep them in separate tanks.
second question: no, I would not put a male in with a female. Don't put males in with any fish that look colorful or similar to a betta. When they aren't breeding they're fighting.
third question: bettas like tanks about 5-10 gallons (larger doesn't hurt) without a lot of water flow and with plenty of hiding spots. Ideal temperature is about 78F, and don't go for the tiny plant jars. Bettas cannot survive off the roots of a plant, they need protein found in betta pellets at the store, they starve in tiny plant jars. Tiny plant jars don't offer bettas enough space to move, the water is unfiltered and deadly, and the water is too cold for the betta to be comfortable. Betta jars are inhumane and are the result of people not doing research before owning a pet.
fourth question: I think that a male betta would eat his babies, most fish do at some point.
Fifth question: if a son miraculously survived in the tank to be old enough that his father wouldn't kill him he and his father would probably fight. Fish don't remember their parents, and their parents don't remember them so they show no favoritism to their offspring.
Go for one betta per tank, and your odds are far greater, especially where you can only have one tank at college so you can't separate fighting fish.
Thanks for answering! Like I said (I think I said...) I hAve two turtles in a 75 and am very familiar with the whole heating, filtration 'size matters' subjects and would never think about putting a fish in a vase, I was just making sure that 10 gal is an acceptable size. Non agressive is an important thing and I wouldn't mind having just one beta but I really was looking forward to snails.. (I was actually thinking about just a snail tank but decided fish would make it a better ecosystem and such) I've seen and read things about bettas attacking snails... what's the possibility of this? I don't have room to seperated a snail and a fish lol! Would it be safer to get a female beta with the snail? Tooling "what's the odds of a fish fighting with a snail" doesn't come up with much...
I once accidentally got a pond snail in my betta tank from another tank, probably came over on filter media or a decoration, and my betta acted like it wasn't there. I never saw any aggression or even interest in the snail. I've killed the snail since then, and haven't seen any more.
