Need Feedback on my Aquarium

not sure what you meant by "reefs" cause you have a freshwater tank. but try the link they have some nice driftwood there.
As far as suggesting fishes for your tank, I think is best if you explore that for yourself and get what YOU like not what others think.

you're probably gonna have a hard time finding larger fish that wont eat your guppies. fortunately, guppies are livebreeders and they reproduce fairly quickly, if they dont get eaten. if you have a male and female guppy, i'd suggest waiting til they produce fry to put anything bigger in there.

i got this info from www.**************** :

"Fancy Guppies are best kept in a group with a few male Fancy Guppies and several female Fancy Guppies. Good tank mates for Fancy Guppies are Cory Catfish, Small Tetras such as Neon Tetras, White Clouds, Honey Gourami, Glass Fish, Ghost Shrimp, and African Dwarf Frogs."



i'm surprized that honey gouramis are included, but thats what it says.


here's more:

Quite often large Mollies will attack Guppies. Even though both Mollies and Guppies are often sold as "Community Fish", usually large Mollies and Guppies are not compatible tank mates.

Swordtails and Platies are also not good tank mates for Guppies. Guppies do better with smaller tank mates like the ones listed above.

Do don't want anything remotely reef looking in the tank unless it's made of plastic. Dead coral is calcium and will increase the ph and hardness of the water to untolerable levels by most FW species. Although your guppies could probably handle it for a short while it's not recommended for long term. Your plants would probably die off as well.
