Well, I lost a conch two days ago, and just noticed a large turbo snail dead on the sand with 5 crabs (red leg and blue leg and one unidentified) going at him like they're at an all-you-can-eat buffet. I'm worried that there's something wrong with my tank. Or have my crabs developed a taste for escargot?
Details:
65 gal set up for two months, used water and some live sand from an established tank. Have 15 gal sump with skimmer and carbon to filter. I use RO water to top off.
Tested two days ago after the conch died - nitrates, nitrites, and ammonia were normal. PH was just a little bit low, so I put some PH up in the sump. Salinity is at 1.025. Temp is at 80F.
A couple of times my sump has gotten too low, which made the pump spew air into the tank for a few hours.
There are quite a few baby snails in the tank, and there is algae growing on some of the glass that they feed on.
I have been wondering if I'm not feeding enough (could the snails be starving?) - lately my Yellow Watchman Goby has been alot bolder with trying to get the food, and my serpent star has been emerging for a little while while the lights are on (unusual). I have a tang, the goby, two shrimp and the starfish - I feed a cube of frozen shrimp or some flakes every evening.
Thanks for reading! Please let me know what you guys think.
