I have a 5 year old watchman goby. I noticed a couple weeks back when i was feeding the tank that there was a white translucent blob inside his mouth on his right side with a small tubular opening sticking outside of his mouth. It literally looks like a tunicate (sea squirt) hosting his mouth...

I'm wondering if this is a type of cyano although I've had that before as a purplish sheet of slime growing all over my rocks. This is just a single growth I've had for a couple months and it's nowhere else in the tank. It started off as a dark brown/purple flat velvet growth and has bulged out...

These babies in the lfs are listed only as 'Black African Clownfish'. The only one I come across online is Allard's clownfish (Amphiprion allardi) from east coast Africa. There is a Mauritian clownfish (Amphiprion chrysogaster) that resembles these, adults have a yellow underside. Anyone know...

Starcraft 2 is coming! (vids and gameplay can be seen at Blizzard)

Is Joe's Juice harmful to shrimp? My cleaner likes to pick away at it, he's done it before with no problem. This last aiptasia was pretty large though and the shrimp keeps messing with whats left of it, causing bits of it to float around and the fish end up eating it too. :mad: Shooing a...

Does a 50/50 (6.5K) show brighter than a 10k? I currently have a 10k 15w in my 20g. Which one is better for a fowlr (w/ cleaner shrimp & crabs)?

I'm getting pretty close to buying this one. If anyone has this one or it's predecessor W100 let me know what you think of it and if you have any tank shots, post 'em

I have a 20g fowlr that's been running 3 years on a Millenium 2k filter with no problems. The water surface has always had that dusty look when viewed from underneath, I'm thinking a skimmer would clear that up but I don't have room to add to the back (a portable fan is taking up space also). I...

Is a 20k too much light for a 20g.H fowlr? I need to replace my light and would like it to appear brighter (currently has a UV bulb), I've read the 10k looks yellow. Does the 20k heat up more? I also have some shrimp and dusters and would like to get some coraline growth on the rocks.

I have a 20 gallon on a wrought iron stand that I bought a year ago. I adjusted the feet screws upon setting it up so there was no wobble. Once the tank was set up I noticed slight uneven water level. At the time I assumed it was the floor plan causing it. 3 months ago I changed apartments in...

This translucent thing has slowly been growing on one of my feather duster's tubes. It has 2 tubular openings that when touched will shut briefly then reopen. The only thing visible inside towards the bottom is some yellow fibrous looking wad that doesn't seem to move but might be what...

Can the bottom half of iron stands hold another tank? I have a 20 gallon on a wrought iron stand. I remember seeing a picture of someone having a 10 gallon QT underneath on the 'rack'. Is that safe to do? I have a wooden board on the bottom rack serving as a shelf.

A bicolor blenny was seen entering a feather duster. Bystanders watched the reef-safe suspect with amusement. One witness was horrifed to see the blenny come out of the tube, turn around and yank at the edges pulling pieces off then stuffing himself back in. Authorities were called to the scene...

I read an interesting article for an aquarist magazine how a university quarantines new arrivals through hypo. Not only do they have their tanks lowered to 11ppt (1.008sg) but acclimate the new arrivals for ph and temp, then straight to the hypo tank without going through the 48hr salt drop...

I must've not closed the bag well since the previous mix, this last mix I made ( I use Instant Ocean) had salt floating on top and a small pile sitting on the bottom. This happened before with the last bag I bought when it was almost gone. The salt is also clumped in large chunks probably due...

I have a Maxi-jet 600 PH, 2nd hand, don't know how old it is or if its ever been cleaned, I've been using it for 4 months. How do I open it and clean the impeller, and how often?

Does the display tank have to be isolated from fish after a case of Brooklynella and if so how long? I've read that it's highly contagious buy not sure if its only through direct contact or it stays in the enviroment.

While my tank was in hypo (sans the hermit crab) the golden brown algae on the rock started spreading and turning dark brown/mossy green, in fact it has a thick layer of growth on it that resembles moss, thick enough to move with the current. I noticed a couple of areas where translucent wispy...

I want to hyposalinate the tank for ich but it might be a few days before my refractometer arrives. I know the swing-arm hydrometer isn't accurate enough but can I use it to drop the ppt/sg somewhere above 1.009 in the mean time, until the refractometer arrives? I don't think my fish can wait...

Will these 2 get along in a nano tank?
