so i had a problem with my bichir eating a peace of gravel, and getting "blocked up" he seems to have passes the gravel, but i dont want it to happen again, so today i just bought my sand that i will be replacing the gravel with. what is the best way to do this swap? remove the fish? how long do i need to let the sand settle before putting the fish back in? ect and any tips you guys might have would be much appreciated! thanks all, i think im going to do the swap on friday.. so any info you have for me would be great! ohh and any tips on catching the monsters?
