Who Gives A Fish Forums

Thanks for the tips, everyone. I'll cut back on feeding and test my tap water. Tank's been running for about 8 months, so it's not new. Gonna try adding some frogbit too.

My 75-gallon Discus tank keeps having ammonia spikes, even with weekly 50% water changes. I've got a Fluval FX6, sand substrate, and a bunch of Amazon swords. Tankmates are 6 Cardinals and 2 Rams. Feeding twice a day with frozen bloodworms and pellets. Any ideas why this keeps happening?

Re: "Natural Discus Behavior"

I think I should clarify that discus are shoaling fish. Not schooling fish, there's a difference. You can look it up if you're not sure what that means.

Re: Discus and water softeners

Try searching for "water softener" in the top right search bar. I'd advise against using one, as they work by swapping salt for the minerals they remove. Not ideal. If you're just keeping discus and not breeding, they should adapt to hard water, assuming it's free ...

Re: General Questions: Cross Contamination

James, no worries on the questions, this place is for sharing knowledge after all.

I didn't go through the whole post Pat linked, but I'd like to add that proximity can also be a contaminant issue. Having a quarantine tank helps, but I'm guessing that's ...

Re: Morning Feeding Time

You can see in the video, they'll stick to the glass for a bit if pressed against it. Floating's fine too, they'll still get 'em.

Hi all,

Need some help here.

I've been doing a lot of research on fish care and I keep seeing people recommend floating plants.
I don't have any real plants in my tank yet, planning to get some eventually, but not there yet.
I'm pretty clueless about live plants at the moment.
Are there any ...
