Opinion on L014 and L048 in my ray tank

[squid]

Would like to get your opinions on putting my L048 into my ray tank with my L014.
I feel my L014 has grown quite nicely in my ray tank , I frequently feed massivore pellets to my rays , and rays are really messy eaters. I feel my l014 has grown quite nicely in their tank.

Will it work if i add in my smaller L048, its about 4 inches, My l14 is about 5-6 inches now.
the tank has only 2 caves though

what are your thoughts? i dont feed my l014 veggie pellets though.

Maybe add a few more caves?

thanks. I'll try to give them a few more caves

finally added my L048 into the ray tank, but noticed its sticking to the sides of the tank and not using a cave.
should i be worried?

So far my 2 plecos each have their own caves now. Have not seen much of the l048 though.

This is him in his cave.
