Well, until now, when I had a little Web search, I didn't know that people call syconoid sponges Q-Tip sponges nor even pineapple sponges. :headshake2: What kind of whitish pineapples do they eat, actually? :confused: They may be referring to the shape, only. But I said greenish-yellowish...

Avoid to buy to much of them as they can turn themselves against each other when the first algae blooms are over and food is scarce and territories small. Every tank can be different and look if it's more algae or detritus and where it pops up, on the sand, the glass, the rocks. The glass you...

If there are at least two then they will be constantly carrying eggs as one fertilises the eggs of the other. They are hermaphroditic but cannot fertilise themselves. Raising shrimps is not impossible but needs some set-up and experience. There are some Web sites explaining it in more details...

If it has some green tones in the yellow colour it's often called "pineapple sponge". But that's only a popular name not a species name.

Many sites and people say 20 gallons minimum for clownfish. But in my opinion, 10 gallons for two would be fine as they are poor swimmers. Maybe you leave out the damsel as they are often aggressive. Our damsel is quite nice and is really friends with the single clown but you never know. My...

If you can easily remove them with a turkey baster or with tweezers then it could be cyanobacteria, too. They are called "red slime" but a light green species is also quite common. If you put the particles you have taken out into a jar and leave it there for an hour then those particles would...

Only the peppermint shrimps aren't the reefsafest. It's been told they pick on tubeworms and go sometimes on soft corals. That's the reason why I didn't buy one despite the fact that it would even socialise with my cleaner shrimps as they are both Lysmata species. And my Aiptasia look...

If it's a little crab it could be a "hairy crab" or a "gorilla crab". There is a plethora of species and at the first view they look like a little spider overall if they run away. I got one of them in my pico and it hides always in front of a hole in the rock day and night and seems to ambush...

And then the hermits will become fat and don't any algae anymore. :grinyes:

I think it depends much on the critters in the tank and maybe on the live rock, too, you bought, how much cleaners are needed. In my pico are almost no algae after the initial brown algae bloom. Even the magnetic algae scraper on the glass I use maybe once a week. I even feed the hermit from...

But cowfish are character fish that are worth to keep them on their own. Maximum size is been said only 16" instead of 20" as often stated. But they will need a big tank as already said. Some people had them with puffers but some reported problems, too. If any tankmates, then peaceful fish...

I read too about different opinions how the range of alkalinity should be. Some suggest a low range and other a higher one that starts where the other ends. :confused: Presumably, those different opinions come from the fact that natural seawater has a quite low alkalinity. In the sea there...

But that's one of the least thing a red-legged hermit eats. I got a lonely hermit (pun intended :grinyes:) in a pico with two bigger rocks wit almost no algae on it. There is no fish food or other critters to atatck (tiny gorilla crab and all sorts of pods way too fast). Under such...

They can smother other live by simply covering it. "My bubble algae are perishing ... ":grinyes: Many of my syconoid sponges die from red slime, but those sponges are very prolific, fortunately. And overall corals don't like growing algae on them at all. The majority of my button polyps...

Some author described them as "reef terrorists". They are lazy little villains. Mine, that is Herman, eats even cyanobacteria when he's hungry, but lays lazy on the sand doing nothing for a day or two when I fed him. To get him doing his job of eating algae you need to kick him *** and there...

My Astrea snail eats the small bubbles, too. I simply remove the larger bubbles with tweezers. Depends how big is your tank and how much time you have. :grinyes:

We still don't have a cowfish and maybe we will never have one. But our plan was to set up a large tank with live rock and the cowfish would be paramount in this tank. So, any further addition to this tank would be done only with the cowfish in mind. Cowfish are great character fish like...

My pico is infested with pods. They smaller ones run even at day around the rocks and the glass is full of them. That is because there is only a hermit crab and an itsy-bitsy hitchhiker gorilla crab in the tank. I guess that most pods came with a Chaetomorpha ball from my "main" nano tank...

I got one red-legged hermit in my pico and I saw him actually eating red slime. But he eats only the size of a thumbnail per day and only when he is really hungry. Now, for example he lays since one day between two rocks like a bum on the pavement simply because I spend some tiny piece of fish...

Peppermint shrimps have been raised successfully but it's not a simple task. Mainly it's having the larvae their own tank, water quality and food. The whole thing needs some attention, probably. If you find a Web page of someone explaining it you can try it yourself.
