I have just bought a 120L fish tank and need to find gravel for it, roughly what weight in KG will i

Looking to set up for tropical fish and am also looking for ideas on types of fish to put in it. Firstly need to find out how much gravel i will need. The tank measures 40ins wide by 12ins deep and 16 ins high.

Don't use gravel. Use the little gem rocks. Gravel is much harder to clean and starts to smell after a while. You can get cool stones from any craft store.if ur luck you can find some at the dollar store. You dont have to worry about the fishies eating them or them getting stuck in your filter, plus they are really easy to clean(TRUST ME)..just strain them and rinse with hot water-but cool em off 4 u put them back in.duh!- 120L is like 32 gallons but im positive you wouldnt need 32lbs of gravel.maybe 25 if that. Use your best judgement.

My personal faviorite tropical fishies are Neon Tetras because they are low maintence and very eye catching.. not to mention, the little hot pink ones are so very loveable! But here are some community fish that are beginner friendly:

*Bleeding Heart Tetras

*Bristlenose Catfish (algae eater)

*Banded Rainbow

*Cherry Barb

*Guppy.(easy breeder)

*Swordtails

*Dwarf Neon Rainbow

*Clown Loach

The list goes on and on just be sure not to get Aggresive fish!( I made the mistake of putting my beta fish in with my tank and, even though it was the smallest fish in the tank, it pick on all of my other fishies, killed my little froggie and somehow managed to tear a claw off of my little crab!.BAD BETTA.so i had to put him back in his bowl.by himself.!) When you go to the pet store to purchase your fish ask where the community fish are and explain that you are building a begginners tank and im sure they will be happy to assist you in choosing the perfect fish for your tank. Also i would get an algae eater such as a catfish or snail just to help keep the tank clean!
