Things in my 55 planted are doing great right now. The plants are constantly grow taller and getting brighter and the amount of snails has GREATLY dropped. Last week I picked up seven diamond tetras( 2 males 5 females). They've colored up beautifully and have even tried spawning. The only problem is, this one female is acting strange. She doesn't sparkle like the rest and hides in plants, she doesn't even come out to eat.
She doesn't look sick. Could she some how be stressed? Also, before anyone ask I'm sure she's a diamond tetra.
