Who Gives A Fish Forums

Totally agree with Avalon. Stability over everything. I've seen tanks crash from too many quick fixes. Slow and steady wins the race with Acros. Also, if you're gonna dose, start small. Overdoing it can sketch things out fast.

1.025 is solid for most corals, but Acros can be picky. What's your alkalinity sitting at? If it's below 8 dKH, that might be the real issue. Also, how old are your bulbs? T5s lose intensity after about 9 months.


Yep, alk is huge. I run mine at 8.5 dKH and keep salinity at 1.026. My Acros are ...

Thanks everyone for the feedback, I'm feeling pretty encouraged now. I think I'll go ahead and give one a try, appreciate the input.

Hi Everyone,

I've been noticing some really interesting Symphyllia brain corals lately, specifically Symphyllia agaricia. Their success rate in captivity has me curious. I've come across sites like Liveaquaria that describe them as easy to care for, but then I see threads on forums like this one ...

No way, 2-3 inches is huge. I can see why you guys are saying a 5 gallon tank is way too small now. Those little guys I saw at the pet store were probably just babies.

I've read they can get up to 2.5" in captivity, sometimes bigger, but I'm not sure if that's the case for all species. I've seen some that were pretty small too - around 3cm, but I'm guessing they might still be growing.
