Ok, so we made the mistake of having a puffer in with our ray, hes going back to the LFS tomorrow but now my husband is asking what we *can* house with our ray and snowflake eel...

We are interested in having a few tangs (we know they can have issues with ich and we do plan to QT) and also want a butterfly or two. We did want an emperor angel but to my understanding they arent safe with the rays either.

I do have a horseshoe crab in my 37 gallon now (its TINY, less than 1½" wide) but we plan to move it into the big tank when it gets older.. is there a risk to the horseshoe crab since rays are notorious for eating crustations? What about cleaning the sand in the tank, are we able to have some kind of goby clean it assuming the eel (snowflake) cant eat it?

What choices do we have in terms of a clean up crew (Assuming we dont want to use manual labor, aka ourselves to clean the tank as we try to have as little interferance with our tank as possible) We would like to start adding more stock to our tank but again we want to do things the "Safe" way and not make the same mistake we made with our puffer...

also, this is a stretch but my husband is asking me to ask as we have gotten mixed information both online and in person at our LFS (our friend owns a LFS and has been in the hobby for 20 yrs at least) Can we have a coral catshark in our 125 gallon tank, even if for only a year? Our LFS has made the open suggestion (knowing we wanted a shark) that we could purchase a shark, keep it until we feel its too big for our tank and then get a new one. He would take the then grown shark and place it into his personal shark pond. We get the benefit of having a shark and he gets the benefit of having it on the bigger side.. so realistically (because we do have the sharks best interest at heart) can we house a coral catshark (getting it as a baby) in our 125 gallon tank, assuming it is fed appropriately (not like some people who feed bare minimum to keep small) for any length of time in our tank?

Thanking you in advance for your guidence and help.
 
Cleaning the tank is something that will have to be done regardless of livestock.
HS Crab will be seen as food. Eels can be hit and miss.

LFS gave BAD BAD BAD info about sharks and returning them. When getting one, keep it for life or not at all.

i know we have to clean the tank, we would just like to have minimal interference to avoid stressing the fish. after speaking with my husband hes wanting to get a 300 gallon tank in 2 years (maybe earlier knowing him haha) would we have at least that much time if we got a small coral catshark or other shark? Honestly, im not sure we could part with one of our animals to just "dump" back on the LFS...
 
Personally - I don't believe that a 300 gallon would be large enough to keep a Coral Catshark for life.

To keep a Coral Catshark for life would require a tank/pond with a minimum footprint of at least 24 sq.ft., which with a depth of 2ft equals about 360 gallons.
 
Biggest thing with sharks/rays is that the need to be approached differently than keeping most "normal" fish. Usually, the don't mix well with pet store varieties of marine fish. Species specific tanks work well. Or, if other fish are going to be added, think of small schooling fish. Inverts are almost a 'no' because the will be seen as food. Having a ray will keep he sand uned over. Sharks and rays aren't messy eaters compared to other species, so 'clean up' done from shrimp and crabs won't be needed.

thanks so much for your input and help.. its certainly good to know.

Would they mixed with a yellow tang and a double saddleback butterfly? aside from them all we have is the ray, eel and one pink/blue shrimp goby. If the goby will be considered food we could kick him out of the big tank and put him in our 37 till he gets some size on him.
