>>4984139Not really true. Kubotais are much more vigorous. They're stronger faster and larger, basically double the height from belly to dorsal fin and up to 25% longer. Theyre more energetic at feeding time and spend more time on pecking order. Boraras are quieter, more timid, more exploratory. They spend very little time bickering in the top/mid of the tank as a group and more time exploring and hunting individually, only really grouping up for feeding or when spooked.
IMO it's hard to pick between them since they're so different. Kubotais suit larger open tanks or tanks with stronger flow while boraras suit heavily planted jungles that they can get lost in. They don't mix well either, since the kubotais will bully the boraras out of food 9 times out of 10.
