Don't do it

If your rtc is of 3 inch then your arrowana at least have the size like 10inch

Nope, they don't.

@@zooppetsinc oh! thank you for the reply

@@mairaslam8946 anytime! 😊

The sizes difference must be quite a big gap then.

@@Argalia1st yeah around 4 inches, bro is 15 inches now

@@AqifSaifi bro? So he is a male, huh? What are you waiting for? You have a son, now go out and find a daughter.

@@AqifSaifi but actually, I meant the sizes difference between your RTC, arowana and shovelnose at that point of time.

@@Argalia1st yes I know, the shovelnose was around 5 inches and the rtc was around 9

No you can put I have like that aquarium

Tinfoil barb may jump

No. Please don't put this monster pup with discus.

@@zooppetsinc can I know why pls? If I’am I will put like a very small one and my discus is big.

@@Eve_438 Its in Redtail Catfish's nature to gulp anything that is a food and fits their mouth. It will definitely get big very fast and start harming your Discus Fish.

Idrk about them but I think if the goldfish is very big then yea , but if it's small then it's gonna disappear into thin air like magic🤯

Yet again I'm not 100%

yea they will be all good with them

No they don't.
