i see you're running an ac filter. i do the same on my tank and by the looks of it you took off the grate part of the intake. i've done the same on mine and my starfish crawled in one night had got cut up a bit. i suggest doing a little diy. what i've done is actually cut the grate end of the pipe off, cut the bigger size ring off the tube (the part that fits over the intake in your tank now) and use the big ring to friction fit the grate to the intake. then you have a grate but the darn tube isn't so long. if you need a picture i can try to show you that way.
just a tip!
