Gravel's fine if you're on top of maintenance. I've got a 55-gallon with gravel, and my Discus are thriving. Just gotta vacuum it weekly and keep an eye on nitrates. Sand's prettier, though, no lie.

Keep 'em away from the substrate too. Sand can trap heat and mess with the thermostat. How often you cleaning your heaters?

Yeah, pics would be great. Always cool to see how others rig their frag tanks. Maybe you'll inspire me to finally upgrade mine.

For a 20-gallon frag tank, you'll need decent lighting, a small powerhead for flow, and a heater. I'd skip the skimmer if you're keeping it simple, just do weekly water changes. What kind of lighting you got?


Yep, agree with skipping the skimmer. I run a similar setup with a Kessil A80, works ...

If it persists, consider adding a UV sterilizer. I've had great results with the Green Killing Machine on my 90-gallon. Cleared up a stubborn bloom in 48 hours. Just make sure to remove any chemical filtration while it's running.


Second this. UV is a game-changer for cloudy water. Just don't ...

I had this issue when I overfed my discus. Cut back on the beef heart for a few days and see if it helps. Also, check if your filter flow is strong enough. My FX6 handles my 75-gallon fine, but if it's clogged, it might not be pulling its weight.

Re: Need Help to identify Discus Strain

Thanks a lot guys, really appreciate your help in identifying my discus strains.

Hi Guys, I've been lurking around here for a bit, first time posting so apologies if I mess up.

I've had discus for almost a year now, but I'm having trouble figuring out their strains. I could take a guess, but I'd rather get expert opinions.

They're around 9 months old, some are about 10 inches ...
