I already mentionned that I wanted to have another tank that would be bigger for my bettaboy. Well I finally did it! after cleaning my second hand glass tank I decided to buy a special substrate for the plants and another substrate that goes above the first one. I never worked with plant substrate before so I first looked up how much I would need for a 30 liter tank. after some research I decide to go for tropica substrate.
Ill post more after I bought the plants etc. I doesn’t look good right now! ;D
