Freshwater, the bigger the better!! I have African Cichlids, and clown loaches. Live plants and fake plants.
Check PH about once a week!! IMPORTANT!!! Don't overfeed! Fish have small stomachs, I always see people overfeeding their fish, drives me nuts!!
African Cichlids, clown loaches, rainbows, discus. I have many many tanks!
All kinds :p
The pet trade gets a bad rap for exploiting wild animals but sometimes the opposite is true.
Modern advances in technology affect every industry - even the aquarium hobby.
If you are looking for a unique invertebrate to add to your saltwater tank, consider the sea urchin.
