Hi,

Bought 2 terrapins around 3 weeks back, house them in plastic tank for about 1 week.
2inch-3 inch water with pebbles and a bridge for them to bask next to the window..

About 2 weeks back, change to 23L glass tank.
Initially 10 cm water(9L water) with pebbles and platform. Will climb up the slope but half body submerge in the tank.
Bought 2 live plants 1 week back for them to munch on and help reduce algae growth, increase water level to 16cm ( 15L ), change to suction platform for basking.

Both of them stop basking on platform and instead cling/float on both plants everyday when they are tired/sleeping with head out to breathe.

Both terrapins eating well, pellets/veges as proper meal and ghost shrimps as occasional snacks. Love to swim in the tank especially against the current.
Tank set up, Canister filter, 400L flow with mechanical (3 foam +1 polish) and biochemical ( canister rings ), i.e. 26 times flow rate.

Is it normal not to bask?

Thank you
