I have a grouper I just purchased. It's pink and it is not doing well. I have a 150 gallon tank. I noticed today it has a weird white mossy looking stuff growing on him and it's not swimming just laying in sand opening and closing its mouth. Help I like the fish just want to get him right.

    Angel fish are so pretty! even the guys:)

    Anonymous - 2013-01-27
    I've had a juvenile blue angel for about a month now, took sometime but he is definitely eating now, mysis, flakes, pellets, ect. Also angelfish formula so diet is ok, water paremeters ok, color around head is fading,  know they change color, but afraid this is difficult because it's almost skin tone ish, literally looks like color is disappearing all together? Any advice?

      This is often from stress.  What other fish are in the tank?

    There are a lot of various opinions concerning the powder blue tang (PBT) and its ease of care in a captive enviroment. The overall concensus is that it is a difficult fish to care for, and with that said I would never put too much stake into any one online opinion. Just gather a general consensus from numerous sources and you should end up with some reliable information. This isn't always an exact science like some may have you believe. There are many ways to "skin" this cat!

    If your PBT does not have marine crypto at the time of purchase than you have an exceptional specimen and unforunately not the normal scenario. If your fish(es) do get marine crypto it is easily treatable and under normal circumstances if your fish are heathly they can resist the parasite for some time if not permanently. Tank size has absolutely nothing to do with the presence of marine crypto, you either have it in your tank or you don't. Research the life cycle and you will began to understand your opponent better. Research suggests that if the parasite persists long enough in a captive enviroment beyond the time frame of 1.5-2 years it begins to weaken and the fish can more easily fight it off. This is only one school of thought though. Your best and only sure shot way of curing ick and not killing this sensitive fish along with others is via hyposalinity, which is the process of slowly lowering your Specific Gravity/Salinity to 1.009 to basically sufficate/prevent osmosis of the parasite within its cyst/encrusted covering during one of its life cycles which happens to be the only visible stage to the naked (human) eye.

    DO NOT ATTEMPT hyposalinity without first purchasing a refractometer and doing a healthy amount of research into the correct procedures. This is a long and patient process (4-6 weeks) so you need to be patient and also know what you are doing as with the lowered salinity comes problems of buffering PH levels and increased water changes (often times daily) due to decreased protein skimmer effiencey! DO NOT lower the salinity in only 48 hours like some suggest, DO IT over the course of four or five days min.

    Another thing, please don't believe garlic additives will cure or prevent any marine disease or parasite, why do think SeaChem labels garlic guard as ONLY a food attractant?!? It is not officially proven to do anything else and I have had extensive experience with it myself with no definitive results that suggests otherwise.

    The person who suggested the 6 foot long tank is not far from the truth, that is typically a 125 gallon tank but a 5 foot long 110 gallon could work if the tank is not overcrowed with fish and decor. This is a very active fish and it needs to be allowed the room to move about, length is more essential here rather than tank height and width respectively. Dried or fresh algaes are a must for any tang in concerns to long term health and vitality.

    What about lettuce, vegs? Call me a naturalist, but the last time I was at the ocean I never saw a head of lettuce floating by or brocoli for that matter. I strongly suggest you stick with fresh sea algaes or in the sheet forms from a good (expensive) brand too (i.e. Two little fishes (Julian Sprung's), Omega One, etc.) and also supplement with a vitamin additive such as Boyd's VitaChem or the like in both it's food (flake, brine, pellets, etc.) and also on a weekly basis directly into the water as indicated on the bottle.

    U.V. sterilizers (Good ones, not cheap crap!) are not a perk here, they should be considered a must as well as some cleaners if your tankmates allow it, get a cleaner shrimp and/or some neon cleaner gobies. Many believe that these fish/shrimp do not remove the crypto or parasites from the fish's slime coat as it is perceived to be too far embedded but they are obviously picking at something are they not? It is a good idea to have at least one if possible and they costs very little <$20-$30 max for most areas.

    Sounds like a lot of work and money huh!? Now you are starting to get the picture of what a difficult level of care this fish requires. Those with easy success are not the norm, they are just plain lucky to have received a very hardy individual fish when it comes to powder blue tangs, brace for an uphill battle and breath easy if you are one of the lucky ones!

    My last suggestion is that you should likely only purchase this fish via an online dealer that has a 14-15 day gurantee that is actually applied to this species b/c in all reality you may lose one or two specimens due to poor handling procedures and their difficulty during the acclimation process. It is also believed that the hardier PBT's are collected more closely off of or from the coast of Africa rather than their more vulnerable cousins from the indo-pacific ocean region. I strongly suggest buying a larger sized fish in the 4-6+ inches range as they tend to acclimate much easier than those in the 3 or less inches range. The value is in their survivability which will more than justify the increased costs of the $30-$40 typical increase. You can expect to pay anywhere from $29.99-$99.00 or slightly more if show size, for most PBT's and it all depends on the ocean of origin and the size of the fish. To back up what I have said, search through various online retailors that extend their full 14-15 day gurantee on Powder Blue Tangs. You will find most of these on their restricted species lists, that only will gurantee live delivery and nothing more at the best. There are only a couple that will give you the full 14-15 day gurantee...does that not tell you something about this fish? Good luck, to you and the fish.

    As far as sharks go, this is one of the best suited for captivity. It stays really small, 42 inches in the wild but in the aquarium it is much smaller, around 20 inches though this is highly dependent on the amount of feedings you give them. They can be kept succesfully in a 55 gallon aquarium but a 75 would be much better. If you want to grow him out bigger though you will need at least a 125 gallon. One other thing is that the babies are nocturnal and if you have a heavily decorated aquarium you run a rather high risk of your shark getting caught and drowning. The best way around this is to add decorations a little at a time and slowly get the shark used to bright lighting.

      I have a baby bannded cat shark right now in my 75, he's about a year old now and just over a foot long. He moves around great in there but is getting aggressive now here's what I was thinking. Instead of upgrading now which I can't afford to do at the time, is to trade him in for a baby marble. But what I want to clarify is that this guy (the marble) will only grow half the size of the bannded I have is this true? I have been looking around and I'm finding that most sites say that marbles become the same size maybe just a few inches shorter then that of its cousin the bannded. If this is so a marble would be a lot happier in there then the baby bannded.

    I have a porcup[ine puffer I bought a week ago now named mugsy. I have been trying to feed him a variety of foods from clam, brine, freeze dried krill, shrimp, and mussels. I haven't seen him eat the food yet. It's gone but I believe that is from my snowflake eel coming out and taking. Any suggestions on what I should try?

      Try using tong and feed him directly.  Once they start eating its hard to slow them down.

    The term for when a fish changes its gender is sexual dimorphism. These are a great temperate species but are very territorial. So make sure their line of view is disrupted as they go by an 'out of sight, out of mind' way of thinking although some bickering will always occur.

    I'd like to know what would be a good number of these Chromises to add in a 75 gallon tank ?

      How many inches of substrate do you have and how much in the way of decor?

    We just started our Saltwater aquarium about 2 months ago. Everything is great! We purchased a Talbot's Damsel. We have been watching him closely and he has been picking up shells and moving from behind a piece of Coral. Is this normal? Nesting? He is really a lot of fun to watch! Has any one else seen this activity.
