Its definatly not L66 or L260 as I used to have these when they were juveniles and never were they black and yellow so its def L333, in fact it looks like my current baby L333's
Also I would like to add the water can range from 24-30 degrees

Saying for definite that's is 333 is completely an utter wrong when it comes to juveniles, 260, 333, 66, 340 infact most juvenile hypan species are indistinguishable at juvenile stage simply becasue they all look the same, as on many accounts do 134 which isn't even a hypan species.
The temp range you gave can infact be given, ideally it shouldn't and low to mid 80's is what you should be aiming for to keep them in tip top condition and thrive.
I will admit the fish in question is probably not a 260 becasue of the size and i stated that after size was given. as to yellow and black, many people including me have had yellow based 66's as have many will say they have white based 333 so giving a definitive ID becasue of colour is completely wrong and shouldn't have been said. Infact ive also had more of a yellowy based 260 so just goes to show how IDing juvenile hypans isn't as easy as just saying yes for sure it is either this species or that species.
