How many inches have you got? by Pete Wright
We are talking Freshwater Tropical Fish here, so keep your mind clean!
There is the oft quoted one inch per gallon rule of thumb but this should really be in large quotes and with red circles round it as it really only applies to certain common species of friendly fish that are generally small in size and nature.
So for example a beginner (once the water chemistry is right) with a 20 Gallon Tank might get themselves 6 neon tetra, two mollies, two platys, 4 guppies, and a small Plecostomus. However it would not work to have two discus fish, two small Oscars and four lake Malawi cichlidsâ
