The dirt tank sounds kind of fun to try and experiment with but I think I might just try and change the lights and buy fertilizer for my plants first. I didn't know they made fertilizer for aquarium plants. I don't really have the money to buy a CO2 tank. And that was the only pictured I had on my plants. I know the plants were a long shot with cichlids but so for my fire mouths have left the plants alone and haven't tried eating it or digging it up. But the plants are going to go into my 3 are guppy tanks cause I need more hiding place for the guppies especially the babies if the mom has her babies before I can switch her into my breeding tank to raise the babies, I've had that happen and the other guppies eat most of the babies before I can get to them.
