This is my kids(son/daughter) tank. They both wanted a little something in the tank. So I had to with the pink gravel for the girl and sponge bob for the boy. They have 2 goldfish, 2 frogs 1 kissing gourami, 2 neon tetras, 4 white clouds, 1 betta, and 1 bala shark. They both picked out different fish, so it was kind of interesting doing it the way they wanted it but it worked out.

Wow a bala shark :? wach out they get big.

Hi usmc,
I know you meant well to make your children happy but we also need to choose the fish wisely. Maybe try to let your children understand that some can grow big.
You may try to change the bala, kissing gourami and goldfish with tetras instead. Try bleeding heart tetras, glass bloodfin, cardinal tetras and lemon tetras. They stay small so you won't have to rehome them compared to the other 3 fish which can reach 20 cm and above.

Good luck and nice tank.:D

I know my wife's brother had 2 that got to about 8".

I agree with Blue. Some fish (like the ones mentioned) will outgrow your tank, even if it's very gradually. You're better off sticking to fish that won't outgrow your tank. And make sure you only get community fish. Aggressive fish tend to cause problems :wink:
Otherwise its a great tank 8)

In 2 months my kids are getting my 72 gal for there freshwater fish and I'm getting 150gal reef ready system. So as long as they don't grow to big from now till then. Do you think they'll make it. If not I guess I'll go with blue said.

They will, mate. Don't worry about it as long as you plan to keep them in a larger tank in the future.:)

They will only be in that tank for the most 2 months. I'm just wanting till my tank gets here so I can transfer my fish to the new one. Thanks :D

nice setup i like the pink gravel

It's a beautiful set up, even though I am surprised to hear about goldfish with the tropical fish. If you are moving them to a larger tank it shouldn't be a problem (are the goldfish tolerating th heat, or are the tropicals doing well in cooler waters?) Good luck with your reef tank; we have one at the office I work at, 180 gallons saltwater, its' gorgeous! The saltwater fish are very colourful, and the living reef is interesting.
