What is the best substrate for a oscar sand or gravel? I have experience with using gravel, what is easier to keep up and how to vacuum sand without sucking it all up?
Can I add chopstick snails to release the games for me they burrow in the sand, but would the oscar eat them?Cleaning sand isn't hard. I use a regular gravel siphon and just hover it really close to the top and it picks up the junk. Sometimes a bit of sand gets sucked up but I use a bucket and dump it back in the tank with the clean water. I have light cichlid sand and you will see it start to turn grey in spots. That just means it is time to move the sand around to release any debris and gas trapped. Oscars dig so you may not have to do it very often or at all depending on how active he is.
I'm going to be using a fx4 filter would that be plenty?Keeping Oscar's require powerful XL filtration. The big powerful HOBs or canister you choose should provide plenty of aeration & circulation for the Oscar.
