help with securing rocks
so i plan on getting african cichlids for my tank and i have ALOT of rocks atleast 75lbs of it, anyways those guys like to have caves and things which is no problem but im afraid of a major collapse if they get to aggressive digging. what home depot or lowes product is safe to use and works best for doing this? is there any way to do this with the tank full of water, like a putty typoe of stuff that will hold pretty sturdy underwater but is aquarium safe at the same time? Thanks, Money

I heard of some one use ing silacone. But i just put the rocks clear down to the bottom glass. An start staking from there. Then put your subst around the rocks. Mine have never collaped. I like to change the tank from time to time. So i would never do it permanite thats me tho.

What kind of af cichlids are you wanting to get? I have a breeding pair of red zebras and yellow lab or electrice yellows. They both have breed in my tanks. The red zebras are wild caught. and the yellows are tank breed.

i do know they make an water safe epoxy (sorry, dont know brand name) that is specifically used for corals and rocks........I have never used it so i cant comment on the integrity of it............I do know it can be ordered thru "That Fish Place" in Lancaster PA via their website......Hope this helps

I have heard of saltwater people drilling rocks to connect them.
Don't know anything about it myself, but might be something to look into.

Although, I am not sure if it is possible to drill the rocks you have.

If the rocks are large enough--gives them weight, and remember in water they are not as heavy as in air so they will more easily topple under water than in air--and rough and flat-like rather than smooth or rounded, they can fit together fairly securely. I used limestone rocks like this years ago for rift lake cichlids. Lowest rocks on the tank bottom and build up, then add the gravel.

Silicone will hold them together, and is certainly recomended for smaller, smoother rocks that would easily slip. Glue them in place and leave for 24 hours before adding water.

thanks for all the imput guys as far as what fish im gunna have ive picked samerican cichlids and definately want atleast 2 eart earters. but those guys are very active sifters and diggers. my rocks are down to the bottom of the tank but i have alot of caves and things but im afraid of a fish zipping buy and it sliding off and causing a smush. sounds like i might have to drain the water and refill it again. i coul;d always drill them and add some type of pins in there. stainless steel doesnt rust right? im just concernd about metals leehing into the water. money

I think stainless steel can rust.
Maybe some type on plastic rod or plug. Nice thing about it, if you decided to disassemble for cleaning or to redecorate, it would be easier to do, if the rock are not glued together.

Sounds like a lot of hard work though.

usually you gotta work on something to get good results im willing to put in the effort i got some pics too btw im gunna start a new thread on them here in a min.

twistermom is correct stainless steel will eventually rust over the long could take awhile for it to happen, but it will rust......even really high grade stainless thats submersed will eventually leech something in the water.........puttin a fork for veggies in your tank is another story, becuase its never (at least in my tanks) in their real long........i would either use the silicone safe for aquarium use or the coral epoxy i mentioned earlier.......good luck with the earth eaters.........very interesting fish, never kept them myself...........Let us know when you get to see some pics!
