ok so yesterday i got my 1st set of live stock for my new 120 that has been cycled for about 2 months now. its a 120 gallon tank with a 24 inch 2x25 wat t-5 light setup hanging from the cieling above the tankl...for filtration i have a 15 gallon wet/dry sump filter and substrate is very fine black sand...i went to lfs and got 2 juv. silver arowanas and what they called a teacup ray ....im not 100% on what kind of ray it is but after doing some research i think it is a male reticulated ray. as for decorations i have absolutly nothing in the tank but the sand and a long airstone. while i was at the lfs i picked up 20 ghost shrimp and 20 small guppies hoping the ray would eat and i did witness the ray eating two ghost shrimp. its kinda cool how the spit the shell back out.. i do have an issiee tho one being i think i may have to much current in the tank because the smaller juv. aro stay right where there is not to much current and when he ventures over to the more turbulent areas he seems to get blown around. also i looked in my sump this morning and saw that there were a few dead guppies and shrimp. attached are some pictures taken with my cell phone so they arent to great but let me know what you think and what kind of ray u think it is. thanx
