Who Gives A Fish Forums

Thanks for the advice. I'll set up the 20-gallon tonight. Should I keep the lights dimmed?

My Discus pair started fighting after laying eggs. Should I separate them or let them work it out? Tank is 55 gallons, temp at 84F, pH 6.5, with sponge filter and driftwood. They've been together for 8 months.

Has anyone tried ceramic cones? I saw some at the store but wasn't sure if they'd work. My tank's 30 gallons, with a internal filter and gravel substrate. Temp's at 82°F, pH 6.6. I do weekly 25% changes.

I tried Cryptocoryne Wendtii in my hard water tank, and it's been growing slow but steady. Not as fast as others mentioned here, but it hasn't died either.
