Higher Thinking Posted January 1, 2015 Share Posted January 1, 2015 So I've been running my Radion lights pretty high and unfortunately I think I've had some negative fading on my corals because it's too bright. Anyway, I decided to reduce me lighting and the post couple weeks the corals have actually colored up more. However, I've noticed some problems with a couple clams. They seem to have little nips taken out of them. I have no idea if this could be related to sudden reduction in lighting or maybe some other issue. I do have a green canary blenny which I've never seen nipping, but they are a possibility. The clams are always open and photo receptive. 75 gal with custom sump Kh: 8.9 Cal: 440 PO4: .04 Lighting is Gen 3 pro. Hanging about 8 inches off the water. Maxima is on top of rock work (about 18"away from light) and squamosa is on the substrate. Lighting used to be 80% overall with whites and blues at 100. After reading a bunch of other lighting graphs from people, I've reduced it to 70% overall with blues at 100 and whites at only 40. So whites went from 80% to 28% (.7x40). I can't get a shot of the maxima, but here's one of the squamosa. You can see how the front edge of the mantle is chipped at two places. Thoughts?

BeasileyBub Posted January 2, 2015 Share Posted January 2, 2015 That looks like a definite fish nibble to me. Blenny's are always active. I suggest building a little eggshell crate around the clam so it can repair itself. That way if it starts to heal you know it is definitely your fish (it most likely is) and you have the time to catch the little guy. Quote Link to comment Share on other sites More sharing options...
pledosophy Posted January 2, 2015 Share Posted January 2, 2015 I think your wife is really attached to that fish and it would break her heart if you were to get rid of it. Utter despair I am thinking. . . So to save your wife's feelings, I will gladly take both of your clams, and home them in my system for you, free of charge. You will be welcome to come visit anytime you like, and when you come I will give you the joy of performing a water change for them so they will know you still love them. Of course you would have to bring your own salt... I'm thinking every Tuesday at 7:30 am. Please make coffee when you arrive so it will be ready when I wake up. It's a fair deal, do you know what they charge for dog boarding? Quote Link to comment Share on other sites More sharing options...

It seemed more likely than any issue with lighting because I would imagine the clam would just expose more mantle if there was insufficient light, verse deteriorating the mantle. Thanks!

pledosophy Posted January 3, 2015 Share Posted January 3, 2015 Just black, I wouldn't want to put you out [emoji6] I think if the blenny is larger than the eggcrate that sounds like an awesome idea. If it is smaller you might be able to wrap your cage with that extra light netting you have. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Mandinga Posted January 7, 2015 Share Posted January 7, 2015 (edited) Probably the blenny. I'm no mathematician, but when a $20 fish starts gobbling on beautiful clams...well, let's get the fishing bait out! Though im not convinced those are fish bite marks...have you ever seen the blenny looking longingly into the thousands of eyes of the clam?

Though im not convinced those are fish bite marks...have you ever seen the blenny looking longingly into the thousands of eyes of the clam? Yeah, after much observation I think the blenny might get vindicated. I have been watching the tank as much as possible and I saw my stupid pink spotted goby snap at one of the clams. I've increased feeding (vodka reduced phosphates to near undetectable levels so I have room to work with) and have kept up observations. If I see it again, I'm eating some goby sushi.

The weirdest part is that the tears are only on the little 2-3 inch clams. Nothing wrong with that massive clam I added from Douglas' setup. If something wanted clam mantle, I don't know why it wouldn't just eat that. Quote Link to comment Share on other sites More sharing options...
BeasileyBub Posted January 8, 2015 Share Posted January 8, 2015 I recently had the same experience with a wrasse. It started wrecking a maxima I have but I too bought a clam from Doug and it has left that one alone. My theory is that it's too large for the fish to register it as food right away. Either way I did the same clam cage with zip ties and egg crate. I have a pretty small blenny that is actually obsessed with the maxima (he regularly looks like he's protecting it or laying in it) and he couldn't get through. I hope things go well with your clam(s). 1 Quote Link to comment Share on other sites More sharing options...

Higher Thinking Posted February 2, 2015 Author Share Posted February 2, 2015 updates? Pics?I'll get some pics. I started to just increase feeding and it looks like most of the mantle has healed. Maybe I satisfied the fish's appetite and encouraged it to not eat the clam....Maybe it was all just a coincidence, Idk. Either way, last check it seemed like everything was markedly improved.

Higher Thinking Posted February 7, 2015 Author Share Posted February 7, 2015 Kind of a poor picture because the clam was tipped sideways, but you can get the idea. The tears that were there a bit ago have all healed up. Quote Link to comment Share on other sites More sharing options...
Mandinga Posted February 8, 2015 Share Posted February 8, 2015 Nice yeah it looks healthy. Do you have any other clams? Quote Link to comment Share on other sites More sharing options...
