I saw these in the pet shop and thought they looked really cute. I presume you need a really large tank for them? I'm just starting out and don't want to invest in anything ambitious until I am more experienced.
Their colouring reminds me of stones....so Pebbles and Crystal perhaps?
ADFs are actually quite easy to take care of. For a pair of them I’d recommend about 5 gallons. They are quite small. They like lots of natural cover (live plants, turned over pots, driftwood, etc.) they are really entertaining and love begging for attention.
They are actually a very beginner-friendly pet. As long as you are aware of the nitrogen cycle (very important for any
aquatic pet) then I’d recommend them!
