i have three small swords, a fluffy plant (starts with a), three other plants with lots of small leaves and three other plants with big long leaves. the water looks better than when i had a filter! no filter now coz i turned it off coz my kuhli loach was trying to climb up it! and i came back one day to find 2 out of 3 of my female bettas stuck to it. they are fine, but they are happier with just plants. they happy.
my kuhli loach comes out more now!
