Ruturaj give it about a month or so and I think he will have completely regained his kok. As far as tank size they’re in my quarantine setup for right now until I move houses in a few weeks. I already have a 67g long(48x18x18) ready to set up for them. This specific bichir is a delhezi and is one of the smallest polyptyrus species, they recommend a minimum tank size of 55 gallons and this is a much higher footprint
That seems like perfect size tank for these guys. What I really wonder is how big your fish will grow, since it is seems to have longer body. May be more than 12 inches.
