hi, i was wondering if a 10 gallon tank is big enough to house 2 or 3 kribs (1 male, 1 female or 1 male, 2 female) i just want a small tank so i can put some kribs in. if this is ok what should i use for the inside, like sand or gravel, heavily planted or just some plants, what else like wood, and caves, any help is needed becuase i am new to cichlids and i hear kribs are really good hardy beginner cichlids. anyways like i said any help welcome!
