ALEGIAquarium Decorations Cave Ceramic Sea Shell Decor, Rock Cave Decor for Shrimp Cichlid Hiding Fish Tank (Sea Shell A)

A lot bigger than i was expecting (i have an 5.5 gallon tank for reference) Arrived in one piece wrapped throughly with bubble wrap. My fish seems to like hiding in it

Super cute! Might get another one! Perfect size too. My dojo loaches love it.

I wasn’t expecting such a large & high quality deco but it’s gorgeous! My angelfish agree! I put my bubbler inside the clam shell for a cooler look! Love it!!

The media could not be loaded. My pictures are a little murky because I stirred up all the gunk. There are no sharp edges, the inside in the bottom is smooth. This is a perfect little house for my beta.

The media could not be loaded. The box was fine but when I opened it the shell was broke in half. I’m not happy!

This is perfect for a small aquarium. It is well made and sits nicely in the bottom of the aquarium. It's easy to clean, when needed. The small Tetra fish really seem to like it. Overall, it's great!

I bought this product about a week ago but I did not put it into my tank until roughly 3 days ago.Today is the third day and I noticed the "glassy" coating started coming off, and all but 2 of my fish were hanging out at the surface of the water gasping for air. One of the two fish that was not at the surface, my guppy, stayed in one little spot at the bottom of the tank with a kind of... twitch-like movement and occasionally swimming around in a 360 degree circle. Since I keep a very close eye on my fish (I only have one tank containing platies and a single guppy) including the water parameters and general maintenance, I knew something was up. I tested the water and all the parameters came back fine, but most of my fish were behaving very oddly so I knew regardless of what the parameters were I needed to do a water change - even though I did a large water change only 2-3 days prior when I first added the decoration. When I removed the product (the white sea shell ceramic decoration) I saw very fine shiny particles - almost like a dust - came off of the product as I was lifting it out of the water, and unfortunately my fish began eating these dust particles because they thought it was food... I'm writing this review the same day so I do not know the affects that may or may not have on them, yet.Immediately after doing a 50% water change all of my fish started behaving normal again. No one is gasping for air at the surface at all anymore. I know this result has nothing to do with the general water parameters because I tested for PH, Ammonia, Nitrite and Nitrate before doing the change. The PH was normal, Ammonia 0, Nitrite 0 and Nitrate 5.TLDR: Added decoration, three days later my fish exhibited very odd behaviour - almost all of them were gasping for air, tested parameters and everything was fine, took decoration out of tank and it left strange shiny dust particles behind as I lifted it out, did 50% water change and fish *immediately* behaved as normal prior to adding it.
