I noticed the other day when walking by my gourami was stuck in an opening in my ship... it has plenty of huge holes and 3 small holes and he tried to fit thru the middle one. I quickly helped him get out and one of his feelers broke and he has scales rubbed off on both sides!!!! what do i do i have been monitering him closely the last couple of days and it really dosent seem like it affected him to much......except he avoids the ship now.
