Questions & Answers

10 Customer Questions

The openings look small, I have Red Blood Parrot Fish, do you think they could fit inside without getting stuck, they will be 5-6" when they get grown?
Answer by ChewyMar 07, 2018
The opening for the small rocks are 1 inches, the openings for the medium rocks range between 1.5 and 2 inches, and the openings for the large rocks are 2.25 inches.

how big of a tank is recommended for all the stones?
Answer by ChewySep 30, 2018
The amount of stones that can be used in an aquarium greatly depends on the amount of fish in the space. With this in mind, all 15 stones should not be placed in an aquarium smaller than a standard 38 gallon tank.

The color of the stones are on gray or beige?
Answer by ChewyAug 17, 2018
This stones are grey in color.

Is there any reason to be concerned about stagnant water inside of the caves?
Answer by ChewyMar 21, 2021
Some think these stones look better and better as the algae grows on them, and your aquarium environment looks more and more like the bottom of a natural lake, but, some people like the look of the fresh stones when they are first put into the tank. So, to remove algae from the stones, you can scrub them using coarse salt as a cleanser ( no residue of cleaning chemicals to worry about) Or, put them in a cold oven and put them on bake at 300 degrees farieght for about 15 minutes and then let them cool down before you remove them. Then the algae will come off even easier with a stiff brush and water.

Nice caves, if they all make it!

All the caves arrived in the guaranteed time frame. They are the ones recommended and what I wanted. The packaging was marginal and couldn’t have been from the manufacturer, unmarked, unlabeled without the underwater galleries packaging. Three of the mediums in two different boxes were shattered. Best customer service could do was refund $6 per cave. They claimed to not sell them individually and not enough were broken to constitute a reship. Too bad the small ones didn’t shatter are I believe they are too small for the cichlids but could probably house some fry.

they look nice once you get water on them!

I got these quickly and without a scratch, I would recommend though to rinse them off. They are either dusty or the excess coloring stuff is coming off, just rinse them off and they should be good.

These Will Do

Firstly, let me start off by stating that they do look beautiful in the tank. Shipping is always fast and they were packaged well. They are easy to stack in many ways and my fish love them. I have a 40 gallon breeder tank with three female convict cichlids. They range in size from just an inch to two inches in length and varying degrees of height. Having said that they couldn't fit in most of the smaller (over half of the rocks) and I had to modify them all. I didn't see a point in returning them as I'm good with tools. I simply took my corded drill with a hard sanding bit, used a little water (to keep the dust down) and bored the holes out that needed it. Now they can fit and actually use all of them. One was broken but I just sanded the crack down. I didn't mind this so much as all of the holes are a little too uniform and this allowed me to customize the aesthetic. Due to the small holes I wouldn't recommend these to cichlid owners unless they only have juveniles that don't get taller than an inch. Most cichlids do.

Great collection.

Really cool ceramic fish hides, I did get the order delivered the next day after placing it and I had 2 of the caves arrive broken. I called customer service and they replaced my order that also came swiftly. This time it was placed in a smaller box and they all arrived safe. I barley did any cleaning as they were fairly clean and just yesterday I placed them all in my 55 gallon tank. Definitely a beautiful addition when added with plants.

Cichlid Aquarium Stone Caves

I ordered these Underwater Galleries Assorted Cichlid caves to place in my 55 gallon Yellow Lab species specific aquarium. Chewy had the best price on the internet! Ordering was simple and I received it days before the estimated time of arrival. I will definitely be ordering from Chewy again for all of my aquatic needs.
