So I am guilty of not doing any research on these fish before I bought them. Kinda just an impulse buy. Once I had already brought it home is when I decided it would be a good time for the instruction manual. Anyways I foresee a possible problem. Maybe I am wrong and really hope I am. My concern is the gravel I have is to large for him/her to get the food out from between it. My rainbow shark and Cory have no problems idt with their small mouths. But I'm not sure about this guy and I just got him so I have yet to see if he can eat. I attached a picture so you can see what I mean. Lil guy is hiding in the back, but u can see what I'm saying with the gravel. What do you think? Any personal experience with this? Is it an issue at all? Thanks for you input I'm loving this fourm btw!!
