Leyouyou520 4 Pcs Aquarium Fish Tank Filter Bottom Isolate Net,Grid Divider Tray Egg Crate (11.8 x 5.9inch,Black)

Perfect egg tray. Used this for my aquarium to prevent sudden sand movements.

great racks however not big enough squares for standard plugs

Partition for my fish tank

just the “crates.” 4 separate pieces of plastic/crates. this does not fit a standard 10 gallon tank. it is too wide. you would need to trim but the crates are too thick to use with scissors. ill have to go look for wire cutters. also does not come with suction cups as seen in videos. so... how am i supposed to stick it to my tank even if i sized it to fit? it’s a lot of work. i’ll just buy a smaller tank to separate my fish instead. also the segments are very hard to connect. i had to force 2 together and even then i had to tweak an opening with scissors/tweezers. probably better with an x-acto knife but i dodnt have one laying around. two of them dont fit at all. this is supposed to make my life easier!!!
