The tank is 20 gal divided between my two bettas (male & female) with live and fake plants, moss, driftwood, etc.
60cm long, 30cm deep and 40cm tall.
I'm not sure what the specific breed the glass catfish are, but the store said they grow to 8 or 9 cm max (~3.5 inches)
i believe the water is around 7pH and 5dH
I dont have any artificial light for my tank, it's near a window that gets very little direct sunlight, but enough for my plants to glow.
Thanks Bombalurina for the in depth answer
I had my eyes set on the glass catfish
they're so cool...
I can't have anymore tanks, mum hates them unfortunately even though everyone else disagrees...
