I brought a breeding pair of super reds 3 weeks ago.
They were quite shy for the 1st week,but then they were out and about a bit,the male would pop out as soon as i slid the glass lid across.
Noticed that he had stopped comeing outside his cave for a while.
Had been doing daily 20% water changes as i do too all my tanks.
Whilst cleaning,i carefully looked inside his cave and he has wrigglers in there,i am over the moon.
Must have spawned within 2 weeks of me haveing them.
