About a month ago I bought 2 baby green sev for my 500l they are growing steadily fast for what I have read about sevs the larger of the two is now over 3inch from 1.5 and has no stripes apart from one just before the tail fin the smaller just over 2inch has stripes along its whole body , do they loose the stripes or will they stay I know eventually il be rehoming one of the two and don’t want to rehome one that may have rarer patterning so to say
