How fast do red tailed catfish grow?

  • We are currently upgrading MFK. thanks! -neo
Awesome! Thats what any responsible fish keeper would do. :thumbsup:

In the spirit of not derailing this thread... They grow very fast. If you don't have the final lake set up yet, you are going to have a very hard time upgrading tanks faster than it grows.
 
1.5 inches per month if fed right, about 24inches in a year has been seen when starting at just 2 inches.

I meant 1.2 meters although I have seen 2 meter ones in giant tanks.

I think that's bs. They world record hook and line was just larger than 5'(62"ish). The only report I've heard of one that Big in an aquarium is in a 200,000 gallon public display in Dallas.

All fish in aquarium grow bigger than in the wild, but I say 1,2 meters and you say 5 feet which equals 1,5 meters..

Depends on the size of the aquarium. If you have like a super massive (just for conversation) 50,000 gallon or more, then they'll get bigger than in the wild. But on average I don't think they do. I have seen a couple 4 footers but I mostly see 30-40 inches. I'm no fish keeping expert but IMO one (provided an incredible filter) rtc will do fine in a 8' x 4' x 2.5' pond because they usually don't reach their full potential unless there given extreme tanks. My LFS kept one in a 480 for 13-14 years and it only got 3.5 feet long. Sorry I'm not sure what the metric conversions for these are.

How big will a rtc get in a pond as big as mine? It's like one of the last pictures. Sorry they won't transfer to my phone. Take a look and how big will one get in this size pond? I'll grow him out from like 1" to up to maybe 12" then ill drop him in the pond
