I picked up a pair of lettuce nudibranchs to clean up a bryopsis problem in a 20g I keep. They made short work of my problem algae, but they have tripled in size in a couple of months.
I'm getting the feeling that they are going to starve in the future. Can anyone advise as to success...
I have a 3" queen conch that I kept in a refugium for a year. When I moved it to another tank with one sole lawnmower blenny I noticed that it's behavior completely changed. It used to be our primarily during the day. Now it hides during the day and comes out primarily at night.
Regardless...
Have you ever seeded with live sand in the past or are your critters the pods and bristlworms that come in on live rock? Do you have quite a bit of live rock in the system? Do you have any spaghetti (terebellid) worms?
If you just have the standard stuff then I would just wait a week. If you...
Depends which medium the infauna prefer and where they are located in the existing substrate.
Amphipods, for example, would actually prefer the crushed coral so they are unlikely to migrate at all. Most polychetes will prefer the sand but the ones located far from the margin may never know...
The primary function of a dsb is denitrification. If you aren't currently having trouble with nitrates the I would forego the refugium dsb and dedicate as much of it as possible to macroalgae and critter production.
I need to move a jawfish and my first attempt with a net failed and left the jawfish pretty freaked. I've had this bluespot for about six months and I don't want to stress it any more than necessary. Can anyone with success in this area give me some advice? I have typically netted fish at...
I use the smallest horizontal model, I believe it is the 210, on a 30g tank/sump setup. I like it very much. It does an effective job. I especially like the fact that it releases almost no bubbles back into the sump.
If you do go with a jawfish, get one, not two. Even mated pairs don't share the same burrow. And they prefer their burrows to be several feet apart in nature. This is one of the reasons people have trouble keeping jawfish healthy. Crowding causes stress. Also many aren't provided with...
I have pushed the envelope a few times in terms of fish in small tanks since small tanks is all I keep. But I don't know of any fish that are recommended for a tank as small as a 5g.
It can be done. But I wouldn't think it very kind to the fish. The striped gobie, maybe blackray/highfin, or...
My hitcher did turn out to be an unusual species of rock boring urchin. I'd never seen one that flat and where the spines all radiated horizontally. I did find an image. Thanks for the suggestion Chucker.
