I just got a rehomed bamboo. She is a female and yes my lenny is a male. She needed a home and we are in the process of building a bigger home for our guys so we took her in. But when I put her in Lenny grabed her fin and wouldn't let go. Now I know this is what they do for breeding but they are both only 2 1/2 yrs old so I thought they would be to young. So is he trying to hurt her???? Should I take her out??
