No, it will suffocate in the bag. Move the decor around and try letting it out.
Not trying to be mean to you, but your stocking is very bad:
* swordtails should have a 3+ ft tank
* peppered Corys should be kept in groups of 6+ and, in my opinion, need a 3+ ft tank
* zebra loaches are also schooling, so should be kept in groups of 6+ in a 3+ ft tank
* bristlenoses need at least a 3 ft tank, with no more than one male per 3ft tank
* kribs are aggressive, especially when breeding.. a pair should not have any tank mates in a 54 litre tank (which, I personally think is only suitable for breeding, not as a permanent home)
Basically, in a tank that size, I would not have expected anything else form the male.
