I saw my Lysmata amboinensis shrimp with a piece of scarlet hermit in its mouth, it looked like chocking with too big piece if it... It was definitely crabs curved abdomen in shrimps mouth! Shrimp was hanging in the back glass just above hermit crab remains. I could not see crab shell near by so it...

Is this normal??? With me...

I have a 45 gal aquarium in my basement set up as a giant filter for my two 45 gal sal****er aquariums in my living room. My question is what kind of pump do I need to get to pump it 14 ft or more in the air. All of the pumps I look at I don't think are really designed for more than 4 or 5...

I have a lunar wrasse that has become bit of a problem and I would like to remove him from my tank. Unfortunately, I have a 450 gallon tank and cannot (will not!) tear it down just to get him out.

I've got a 29 gal. to which I'm going to add a small 12" hang on refugium (bought from acryliccity). Will it be OK hanging on the side or must it hang on the back to avoid overly stressing the glass?

Just curious if anyone had feedback on a " G-1 Protein Skimmer" or a "Amiracle sump system". Also any feedback on a " Gen X Pump". These items were recommended to be by my LFS for a 90 gallon setup that I am puting together over the next week or so. Thanks in advance for any info

My new 80 gal reef tank experiences a lot of evaporation - 2-3 gal. a day. There are no leaks. Is this normal? Is there an auto top-off system available that doesn't require a reserve tank? I'd like to run a water line to my sump and setup a system to automatically replenish the water when it's...

Well, I'm gone for two weeks (not that I've been noisy enough for anyone to notice my absence)... Getting married and all that... you know what this means? A: I've been lurking/talking for 6 months now. B: Soon, *very soon*, I'll be able to start setting up my tank! :-) And, no, just because...
