red tail catfish

Question
Dear Will,
         I have one peaceful 6 inch(15 cm) red tail cat fish in my 100 gal tank with two sucker fish(8 inch each).
         Can I put one tiger oscar of 4 inch and one giant gourami of 4 inch altogether into that tank?
         Please advise.


Regards,
Nay

Answer
Hello
Short term: probably.
As silly as it sounds, 100 gallons is tiny for all of those fish. Especially the catfish.
All of these fish are territorial as well, so I would
Not keep all those fish in there any more than a month or two.
Not to sound sarcastic or condescending, but a swimming pool is the best long term tank option for those fish.
