Male Fighter In Arcadia Arc 20l

[j.marsland12]

I've had my arcadia arc 20l for 2 months now, I've currently just housed my RCS with a male betta , he used to be in a 190l and never jumped but then one of the female betta's started acting aggressive to him and other females so he had to go into a breeding box while the female went into a 60l tank with guppies. While the male was in the breeding box he never once tried to jump out.On the Arcadia Arc it has very large feeding holes and I'm scared he may try to jump out while i'm at work and die. Can anyone confirm they have housed a betta (male preferably)in an Arcadia Arc tank and tell me if it is safe to keep him in there or if he will jump out. I'm going to make a replacement lid when i get time next week.

He was probably stressed while he was in with the females, they really shouldn't be housed together unless for breeding..
He may jump, so best to cover the holes just in case
