Can chromis be kept singly or must they b kept in a school?

Yeah I wouldn't mind a small school I just really like the chromis. Not a big fan of cardinals I just like the way the chromis looks

Ok my question is could I keep three green chromis in a 20 long with a pair of clowns? Or could I do one clown one firefish and the 3 chromis or 1 clown a royal gramma and the chromis? Are any of these stocking lists plausible or am I just dreaming?

The reduction potential of an ion is its ability to reduce another ion in a reaction. Or more simply its ability to oxidize. Reduction is the gaining of electrons by a substance and oxidation is the losing of electrons. Therefore the substance that is oxidized is more positive and the reduced...

1 clown 1 firefish and the royal gramma? Is that fine or do the clowns need to b in pairs

Oh well I have a 20 long I just picked up from petco. So would the gramma work with a clown and a yellow tail damsel

Ok. So the clown the damsel and the firefish would b good?

Hi I'm just wondering what the actual minimum tank size for a royal gramma basslet is. I've read on other forums that they have been successfully kept in a 10 gallon or more commonly a 20 long. Live aquaria says 30 gallons so does anyone have a definitive answer? I have a 20 long and want an...

I'm pretty positive it is possible because while I was in cozumel Mexico for vacation a few years back they had started a program with the local high school where as a project the students would says culture a piece of coral then drag it and place the drags back into the ocean where they had...

He said solar system not universe

Hey the great Einstein said religion without science is lame but science without religion is blind

Idk. It seems pretty plausible. Especially considering the first bacteria on earth were anaerobic and could possibly have survived in space. But to be honest until its proven fact its all a matter of opinion.

I believe the theory is that there was intelligent life on mars like ourselves that slowly destroyed the planet as we r today and eventually there was a mass extinction that only bacteria survived. Then a large meteor or asteroid hit and sent a colony of bacteria that eventually landed on earth...

Based on yalls opinions I'd say the real question now is how do we change humanity's relationship with the world from parasitic to symbiotic? Or in terms reefers can relate to if we are clowns how can we protect our anemone ;)

I personally agree 100% with Mr. X. While this hobby is incredibly addicting and does help to generate interest in the marine world and provide lots of intelligence on many species it is slowly destroying the earth. We only have one earth and it is our duty to protect it. As a replacement for...

Well if you wanna b cheap you can get this fixture: aquatraders.com/20-inch-4x18W-T5-Aquarium-Light-Fixture-p/52302.htm Its not the highest quality but if u just need something to last you about half a year until u can get some money it'll get the job done. I've seen it on a couple tanks and...

Ok awesome. So u think the 25 lb nano rocks from Marco rocks will b good if I seed it with 3 lbs of live? Also about how much sand will I need to have about a 3 inch sand bed? It has the same foot print as a 10: 20 by 12

So the absence of coraline won't hurt my tank? Can I place corals on the rock without it?

Yeah thanks that helped a lot! If I get the base rock can I cycle and add fish before it starts to grow coraline?

I am contemplating either getting 15 pounds of live rock or 25pounds of base rock from Marco rocks for my 15 tall. I have a few questions. First how much longer will my cycle be with the base rock and will adding 3lbs of live rock from petco help? Second would the 15 lbs be enough for a decent...

I've been doing a lot of research lately and have really gotten into electronics. I read a few threads on here and decided I am going to actually do something with my summer and make my own lighting for my 15 gallon nano reef that I am about to set up. My main question is can I use these bulbs...

Uhm I'd say about sugar sized.

Will they reduce my need to vacuum the sand with a gravel vac when doinge pwc's?

I'm about to start the set up of my 15 gallon tall tank. I believe I have everything in order. Just need to get a little extra money to get 15 lbs of live rock from Marco's rocks and an api test kit. So my question is do I need a CUC for my set up since it will be a fowlr set up until I can...

Also if I buy 15 lbs of base rock and 5 lbs of live rock how long will it take to seed? Would I be better off just buying all live for 15 dollars more?
