Well, I spoke to Nick from N_E Cichlids last night and confirmed that I was able to get the Peruvian Motoro and the Columbian Motoro that he slashed the prices on! :D Now I just have to wait until next Thursday for them to get here! :( It's cool though, it gives me time to get the 220g prepped for their arrival. I'm switching out the substrate that I currently have for 150 lbs. of quartz pool filter sand and making some DIY heater guards from PVC. I'm also going to eliminate many of the large rocks in the tank and probably one of the driftwood pieces. I'm afraid that my girlfriend's flowerhorn that she lovingly named "Lilly", even though he's a male, is going to get the boot. Other than that, I'm seriously pumped to get these rays! :headbang2
 
Be careful changing out the substrate, you have TONS of beneficial bio there. If you remove that you will lose all the bacteria. It will take time for the bacteria to grow on some where else.

With the large bio-mass of rays, make sure you keep a close eye on your water params if you do the substrate change.
 
Thanks for the heads up! I may leave some of the current substrate as a base, but it's primarily coarse gravel on one side of the tank and silica sand on the other. I just don't want any damage to the rays from the substrate. I do have a Rena XP4 with lots of bio-balls and an AC110 with bio-media running in that tank currently.
 
Make sure your substrate isn't too thick, to the point where the rays won't be able to "turn it over".. If you have "dead zones" in a thick sand substrate, bacterias can build up (unless your religiously syphoning a 220g footprint) and that can lead to disc fungus/rot..

Usually not a problem with big active rays like Motoros, but my Retics need it thin because they don't move much sand..
 
Thanks for the advice guys! I can take one of the bags back since I haven't opened them yet. Any other thoughts?
 
You would think of rays ingested sand and it had a negative impact.. one of the hundreds of raykeepers that keep their rays on sand, would bring it to our attention?

Sounds like an old fish myth .. someone killed some rays out of ignorance and tried to blame it on the substrate..

More like Rays don't like sharp silica sands and that will kill them.. nothing to do with ingestion (my rays spit the sand out when they are sifting for food.. they are pretty good with that mouth of theres)
