Greetings all! I haven't posted in awhile, because life got busy, not because I got out of keeping an aquarium. My 30 gal is still doing nicely. Something strange happened between yesterday and today though. I've had two beautiful orange swordtails for awhile. They were there last night but when I went to feed them this morning there was only one. I figured the other must have died, but it wasn't floating anywhere and it wasn't caught in any plants or decor in the tank. It also didn't jump out of the tank. The other tank dwellers are a school of phantom tetras, four Bolivian rams, and four golden corys. Is it possible that they could have done away with a swordtail overnight? I didn't think any of these had a reputation of being aggressive fish.
