Hey. I just bought one NTT and its about 2" long. I choose it after did some selection among 8 NTT in my local fish store. It was the stable one so I picked it up. But unfortunately after I put it in my tank, it start breathing heavly until now but the other datnoides aren't. Is it gonna be alright tomorrow? I mix it with another two 2" borneo datnoides by the way. Thanks before
