fry help!

Hi all, my sister and her fiance got rid of their tank today and brought their fish back to the Local Fish Store.... Well, I looked in the bowl they were using and saw a baby fish!!! I guess he didn't know that one of his fish was pregnant... None of them looked pregnant to me, but he said that there was one female and male fish of the same species.. they kind of looked like mollys but they weren't.. anyways, i guess all of the other ones died b/c he didn't see them, but there is one in the bowl and it is so cute!! its swimming around and i dont know what to do with it... i have a 2.5 gallon tank but i don't want my fish to eat it, and my tank also doesn't have a heater.. will it survive over night? what should id o?

Ok. First, you don't know what kind of fish it is? You said it isn't a molly, why do you say that? Mollies come in many colorations and body forms. Also, you may want to look into Platies (Platy). They are very similar to Mollies.

Next. What fish do you have in your 2.5 gallon tank? Do you still have the 4 fish, or did you take all/some of them back to the LFS? You cannot put fry in with the Guppies, or they will be eaten for sure. I wouldn't put them in w/ montain minnows, either, but I don't know much about them.

Livebearers are hardy fish, if you keep your temps relatively high (above 70), I think the fry should be fine. However, there could be problems if it goes lower.

Also, bowls aren't good habitats for obvious reasons, but for your fry, the main problem is heat (discussed) and oxygen. Bowls don't have alot of surface area when filled. If you use a bowl, you should only fill it half way (or where the surface area of the water is the biggest). Some people will also use airstones. I cannot recomend them because I don't know what type you want so that you don't blast the little fry around all day. Maybe someone else can recomend something like that.

If you have any more questions, don't hesitate to ask.

Livebearer fry will often survive in unheated tanks at room temp provided it does not get too cool. Some floating plants, even as simple as a bit of stem plant left floating, will give it some security and be a source of food (particles in the plant, not necessarily the plant itself).

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
