I was originally toying with getting a spiny eel for my brackish puffer tank, which currently has a mix of coral sand and marine white sand. However, I'm really finding the sand to be awkward to keep clean compared with my other (gravel) tanks.
I asked if a spiny eel would do ok in crushed coral, but fears confirmed by people that it's too sharp for burrowing fish.
So, I'm thinking now about just leaving out the eel altogether. The online store I order from can't get hold of the specific brackish tolerant species I'm after anyway (they told me to wait to watch their stock lists, but it's about 2 months on and no luck). And, I don't trust my LFS
to order in the correct species for me.
So, my questions are:
1. I know how big the grains of crushed coral are for the CaribSea Florida Crushed Coral brand. But, how do they cope with gravel vacs? Do they still get sucked up?
2. What sort of colour is it once it's in water etc? You can never tell from photos on the web if the colours are 'true' or distorted. I'm after as close to white as I can get, but not so white it looks unnatural. From the pics I can see, the CaribSea Florida crushed coral looks pink, or sorta peach coloured?! Is that right?
3. Any other substrate ideas to recommend? I'm after a 'marine look' if that makes sense (i.e. no eco complete!). pH buffering is not essential: the marine salt I use does that job ok.
