I just bought two rainbows today not knowing they needed a 30 gallon tank. I only have a 1.5 gallon tank will they be okay?

    There's really very few fish that can be kept in a tank that small. A betta could, or a few guppies, most everything else needs much more water and space. Look at getting a bigger tank for them before you have any problems:)

Just got 2 australian rainbows today and put them in my 35 gal with 2 dwarf gourami, 3 neon tetra, 3 tiger barbs, and a scissortail rasbora. They are very aggressive towards each other and are biting at the tetras. The one rainbow is obviously a male and I believe the other is a female, I want to keep them but I do not want them to eat my other fish! HELP!

    These are a great show fish, but they do have special requirements when kept in a community tank. See the 'Social Behaviors' section above and you'll quickly understand why your mix doesn't seem to be working.

My turqoise rainbow female just gave birth to a fry, not an egg. WTF?

    Probably what happened is she laid eggs in the tank somewhere and just too small to notice. They were fertilized and it only takes a week for them to hatch out. So you probably didn't see the eggs and then all of a sudden there is a fry. That is my guess - otherwise, I sure hope you got it on film.

I think I have a baby one of these, I caught it in the creek by accident when I scooped up some water and when I got home realized! It is tiny! And is hard to see! I kept it to see what it grows into! Please tell me if a good baby food for them is sera micron, it eats it but grows slow!

Bosemani rainbow question: I'm an experienced keeper, considering making some tank changes. Need to know what is reasonable for adult Bows concerning tank size. They're 4 to 6 years old.

    How many are you planning on keeping. They need a bit of space. 30 gallon will be good for 3 or 4. They need the length to swim.

I just recently bought some and they seem to like to jump out of tank, any ideas why?

    Rainbows eat insects in their natural environment and swim close to the surface. They jump if they are startled or if they are hoping to catch an airborne insect.

    Because the are jumpers like many fish da ! Mine get really rambunctious at feeding so I dont walk away from my tank with the lid up .

Just set up a 65 gal with 12 Angels, 6 cory cats, 1 bristlenose pleco, 1 male betta.....would 2 rainbows round off the tank or would they be too active for the angels? Thanks for the help.

    Rule of thumb is 1 gallon for each inch your fish will be as an adult. You have to subtract gallons for the gravel, decorations and bedding. The angels can get up to 6 inches - that is a minimum 75 gallon tank needed just for them. The tank is too small for the fish you have already. I would also read up on some information regarding how well all these guys get along full grown. Sorry about that. Maybe a good excuse to get another tank though so more fun.

I bought 7 "Australian" Rainbows, but as they are getting their colors, some have red tail and fins and some have red. Any ideas what these rainbows might really be? Any information will be greatly appreciated. Thanks

    I dont know for sure but perhaps the ones with the red tails are male, because males tend to be more colorful.
