Oh, I misread that. I see now they may have been talking about rejection water. We pipe that right back into our FW systems also.... I thought they were talking about product water.... Jay

What would your goal be for that? For most FW fish, you would just have to add some dissolved solids back into the water. If you are importing South American fish, I could see using a mix of RO and tapwater to get the DS levels down to where the fish will do better - but straight RO water is...

Kev, There isn't anything about the species itself that should pose any major problem, but individual fish can have issues that keep them from feeding properly. Obviously, a fish with major health problems isn't going to feed normally. Overall, these are very hardy members of the genus...

Sorry on all accounts - I don't really have any solid personal data other than what I had first posted. I can speculate that under ideal captive conditions, this species ought to live for 15+ years (but ours died unexpectedly during a strange disease outbreak where a number of fish died in the...

Crister, Less critical than the clown trigger - you should get a positive ID on your "brown spotted grouper". If it in the genus Epinephalus, it could reach a length of over two feet. Clown triggers are highly variable in both their maximum captive size AND their behavoir. Some clowns reach...

Matt, My understanding, (but I'm NOT a lawyer!) is that Caribbean stony corals that are found growing on FARMED live rock are legal for sale in the U.S. However, Acropora palmata and A. cervicornis are ESA listed - so any possesion of those would likely still be illegal unless there was a...

Crister13, I would need to know the lengths of all those fish as well. As a fish's length increases linearily (1" to 2" to 3", etc.) its mass goes up by the cube, so a fish that is a few inches longer may require twice or three times as much room. Also - at some point, the grouper is going...

IDK: I was in an on-going email discussion with my shipper in Japan about getting in some giant crabs, and I haven't received any emails from him since the quake. He is 100 km southwest of Tokyo, so I didn't expect his firm to be affected. However, my guess is that since his company has a...

The ammonia concentration you saw is not congruent with the circumstances you reported UNLESS you added a HUGE amount of food - and if your tank has been set up for a year, I'm not sure how that could happen. Did you have somebody else feed the tank? Another option could be that your ammonia...

Flukes are difficult to control if you have lots of fish entering and leaving a system. The treatment that I use takes a minimum of 14 days. Bascially, you dose the system with 2 ppm praziquantel. After 7 days, change 50% of the water (siphon the tank bottom at the same time) and re-dose...

Thales, Ahh, but that is the problem - if I ask them, I'll get the salesperson's pat answer. This was just a new term for me; it was used on the PL as if the reader would know what it meant, so I just figured that it was a set procedure being used on certain fish coming out of Hawaii. Jay

So, I just saw a 104th street wholesaler listing "Captive conditioned" yellow tangs. I understand the idea behind this, but wanted to know what the criteria for this is - held for a week and purged, grown from post-meta fish or what? Thanks, Jay

Larry, The few that I've grown to size lost their color gradually, so it was difficult to say when there was an "end point". To be perfectly honest, they lose a lot of their attractiveness at a height of only about 4", when they start to get the pale mide body stripe. The red strip on their...

So, do you mean that it is continously showing its stress color pattern? Does it have enough places to get out of sight if it wants? I've seen some of these fish just not adapt well to people moving around the room, could you try observing the fish from a dark room (so it can't see you) but...
