Comparable or not ?

Not a bad looking tank though. I think you're prob fine with the two Oscars size wise. However the bio load will be quite a struggle my advise would be minimal substrate minimal decor to increase flow and as much filtration as you can get and most likely biweekly water changes. If they get along and you can keep water parameters in check youre good. To add anything else would complicate matters and increase upkeep exponentially

With the consensus of an improper bed I will have to rectify that here in the near future..sand? Or gravel? Preference?
 
I think a red tail can survive in a 40 breeder longer then those oscars in the 90.

A bit of trolling is see. Smh

Ive changed substrates several times dont think there is any easy way to do it....just gotta roll your sleeves up and go !lol

I drain out half the water then net out all the sand gravel being that you have dirt you could then siphon out what the net missed. It wont take long if you net out allot. You could just put the oscars in two seperate buckets while your doing this.

Me i would go with pool filter sand. Just clean it really well before you add it
 
your oscars look fantastic :) I'd avoid the other two fish, existing stock is already bio heavy

Yeah also agree on the sand, I'd avoid the MTS though; on the grounds that I haven't seen oscars pay them much attention before, which means they'd be super annoying to take care of if the population skyrocketed.

Good bit of gravel sifting, and removing say half is what i'd do
 
I don't see what the big deal is about the depth of the OPs substrate.
OK, there are 2 camps with differing opinions, some believe deep sand is good for nitrate reduction, some the opposite. Some believe deep sand offers anoxic conditions that can help reduce nitrate, especially with large populations of MTS snails to help keep the substrate from going totally anaerobic.
Some I see here don't believe that.
Until there is scientific proof either way, well.....
I have used both deep, and shallow substrates successfully, (both with MTS snails) and even used the plenum concept, with some degree of success.
Regular vacuuming and large frequent water changes are much more important than substrate depth.

Yup hahaha thats kind of why i didnt give an opinion, you stated this somewhere at some point. Just an idea of how to remove it if ye wanted too.

Ok so I attacked the sand issue....same tank but is a little dirty after the big swap. This wasn't fun but after feedback yesterday I had to do this. 25 pounds of white sand that's it. Went from one extreme to another but I do like the way it looks.

Thanks guys

Wow you dont mess around !!! It will clear up you will appreciate the sand. Much quicker to clean during wc's. I dont even use the python anymore. Found garden hose with a larger diameter and its much quicker.
 
Looking a little better but stIll not the best for those fish. Maybe emptying the tank and keeping a hamster or Guinea pig may be best.
