Well here is my tank, for the tank and everything in it i have only spent around £150 so it is really a budget tank. as you can see there is an air pump going along the back of my tank and from under the ship. on the left side of the tank i have put some artificial grass down to give babies a chance of surviving. in this tank there is mollies, guppies, gouramis, swordtails, plattys, 2 plecos 3 albino corys and 2 African clawed frogs. i haven't got any live plants in there except the 4 moss balls. I decided to sand the bottom of the tank to give it the characteristics of the bottom of the sea. I know its not great but i think i have done quite well with the low budget i was given
