When Do RTCs?

[hick_a_rican]

holy ****... 3 weeks?? you must be giving him more than just shrimp.. LOL he is a nice RTC... mine is 2 years old and is about 8' or so. the red has been vibrant since he was about 10 months.

you might wanna test your water and what size tank is he in? A 2yr old RTC
should be over 2' in length. Mine was growing an inch a week till he hit about 10".

To the op, it will get more red as he gets bigger. Mine started getting it around 6". He's somewhere between 12-14" now, only about 3 months old now.

Fun fact of the day: Flamingos get their pink color from the krill the engorge themselves with. So feed your RTC some krill.

And the ones from Africa get their pinks from cyanobacteria.
