RTC Growth question.

  • We are currently upgrading MFK. thanks! -neo
When I had mine over a decade ago, I would feed it until it has a nice round belly and then fast until the roundness goes away.
Same here. At any age.

Thanks, I can't see his belly though he's in a small pond so I look down on him.
Yeah. It is a matter of quantity and quality of food - how quickly it is digested. Small RTCs can eat a lot of bloodworms, flakes, pellets and their tummy is flat again in 1 day or less. Big RTCs can eat say a fish of several pounds and their tummy goes flat in a 1/2 week to a week. And then everything in between. Depending on what you give them - pellets digest relatively quickly, say a pound of shrimp or lots of chopped up fish will take significantly longer, one whole big fish will take the longest - space your meals accordingly. I start to be more careful past ~10".

Also, fish often will start cruising around looking for food when real hungry, first at night then even in day light. I cannot say I saw that with mine but many report that they go by that rather than the tummy roundness or lack thereof.

Lastly, experts profess it is always better to underfeed your fish a bit than risk overfeeding by any degree. People should not be afraid to provide less food (but still a complete nutritional package). They should be afraid of providing too much.
 
Also be aware of the content of what you are feeding. If you feed shrimp with the shell on and stuff your cat he may digest the soft parts of the shrimp faster than the shells leaving the shells compacted in the stomach, which could cause him to vomit. Same can be said with fish that have very dense bones. A rtc like many predators if it is unable to digest, bone, fur, or exoskeletons quickly enough will regurgitate them in short order. :) I just thought I would throw that in there as I can recount several member's fish in a slightly smallish tank regurgitating in the night and as you can imagine this fouls the water to no end. The fish were all dead when the member woke up. I think it's a rare threat, but something to consider when feeding whole fish, or whole shrimp. Avoid feeding mammals and birds as the hair, bone, and feathers may not digest easily.
