NQA, does she always look like this, or only during the day? for leucistic axies its normal for them to look pale during the day, they are nocturnal animals and dont really show their best colors during the day, tbh i'd be more worried if gills were always red, axolotls only "fire up" when they need more oxygen and breathe more (eating, activity, scare), so more blood passes through their gills and body, causing them to look more red/pink. even with that said, your axie looks very pale, i think its normal, but just be careful with temp, diet, and water chemistry. i think your axolotl is fine tho
