Hyphessobrycon herbertaxelrodi, yup, tough little chaps these, and a very under rated fish. Elegent. Easy to keep, easy to feed and not aggressive.

Tetras are shoaling fish and should be kept in groups, ideally 6 or more fish. Alone, or in small groups, they will be stressed. In a tank that size, you are going to be seriously pushed to find a species that can be housed in that kind of number. One species that is around a lot at the moment...

Green TB's are the same species as regular, (as are a couple of other man-made morphs). They will treat each other the same.

Tiger Barbs are a notoriously aggressive species. With most shoaling fish it is important to keep a good sized group, at least 6 fish say. With Tiger Barbs it is even more important - vital even. The aggression of the dominant fish(es) is then dilluted amongst the rest of the group, nobody has...

Just to add, mods do not have access to the admin panel. Only Will can issue an IP ban.

Phantoms are a naturally shoaling fish, they should be kept in groups of say 6, preferably more. As for the Betta, you'll probably get better answers on the Betta board as it is more a Betta question then a Phantom one.

IP bans are pretty futile really. Most people at home have a lease on an IP, and when that expires, (depends on ISP but rarely more then 24 hours), they will get a new IP from their allocated DHCP pool. What you have then done is placed an IP ban on some random address that could be picked up by...

Does it have Rasbora finnage? My first thought when reading that was a bosemanii or some other rainbow. Many have generally similar body shape and almost all are larger, but they are obviously very different.

As I said above and as HM4 has also stated, your group size for that species is way too small, you need at least 6 and preferably a lot more to keep the aggression evened out amongst the less dominant members. Barbs generally are a very poor choice of fish for cycling, they do not tolerate...

Fixed. It happened with one of the IPB software upgrades.

Very typical when introducing fish into strange surroundings, they clump up with whatever. After they've sussed out the new environment, they tend to toddle off and do their own thing. That said, all shoaling fish kept in small groups will have a residual level of stress, and they can behave...

They are the same speicies. You don't need to consider a group of each.

True shoaling is a defensive strategy adopted by small fish when they feel threatened. It is rarely seen in typical tanks. When threatened they shoal up with their own kind. If they feel REALLY threatened, then with other small species - but if the fish are carry that kind of stress load, you...

My setup here.

BBC hospital ward closures.

I can't see the pictures. If the fish asre behaving and eating normally, and your stats are good, which they sound, then I doubt you have a serious problem. There are 3 fish which superficially resemble each other Trigonostigma heteromorpha, (Harlequin), T. hengeli, and T. espei. It could be...

If you go back and read the original piece, you will note that I presented a number of scenarios, and suggested thet there were others. One of those I highlighted was a continual low level infection managed by the immune system of the host. In your earlier post in this thread you acknowledge...

Paracheirodon simulans, (green Neon), is similar in many respects to regular Neons. They perhaps stay slightly smaller, but are otherwise comparable in difficulty. They tolerate pollution poorly, and if you have ammonia or notrite problems, they won't last long. Once established, they are in all...

Welcome to the forum. I moved this to the Cory board as I'm sure you'll get a quicker response there.

With the Oscars that size, it will probably be okay, but I suspect the Oscars will not tolerate the shark when they get larger. You might want to ask on the NW Cichlids board as it is more a question of the Oscars then the shark. The shark will be pretty ambivalent towards the Cichlids.

Neons and Cardinals are quite sensitive to poor water conditions, it is for that reason you often see advice that says they should not be added until a tank has been cycled and running stably with other fish for 3-6 months. Black Neons and Glowlights are much tougher fish and can tolerate a bit...

As I said above, the piece was unpinned earlier, so the ongoing angst is somewhat superfluous. Rather then taking an unscientific approach, I read various sources, collated papers from several universities and presented a number of different scenarios, adding that there were others. The...

Okay, well all of the above apply. Additionally, the males have longer fins and will be the ones fluttering about spreading their fins in front of the duller plumper ones! They readily show courtship behaviour in clean water.

I have unpinned it. It was pinned because I had several PM's asking for me to do so. I also have read much about Ich, and have also a stack of papers around somewwhere. There are, however, some simple easy observations that most aquarists that have been around for years will know to be true...

Another report from India on the strange deaths of many Gharials. http://news.bbc.co.uk/2/hi/south_asia/7171866.stm

The box was checked by default until a software upgrade some time last year. This was quickly noticed and set back to the default checked state. It is possible that people joining in that period, or otherwise modifying their accounts in some way or other may have picked up the "unchecked" problem.

There is no one single way that works for all, hey, that would be to easy. Generally, (and there are exceptions), females grow larger then males, are less colourful and are noticeably deeper in the body when viewed from the side or wider when viewed from above. If you have a particular species...

I like it being open as well. If I get redirected to a sign up page when googling, I tend to return to the google results and pick the next one. That could just be me being pig-headed about such things. I'd rather get the information needed to a fishkeeper in distress then force someone to be a...

Most barbs, and particularly Tiger Barbs go "nose down" if the water quality is poor. Indeed, there are many aquarists that keep a group in a tank as indicators of trouble. So water trouble is a good starting point. Temperature is only one of several important factors - if you have not cycled...

Mike is right. In small groups, naturally gregarious fish will be stressed and show atypical behaviour which can run from hiding away and slowly dying all the way up to outright aggression. If your tank has the space, (overcrowding can also cause stress), you want at least 6 of each species you...

"Scale inhibitor" - hmmm. There could be a load of things in domestic plumbing that could claim to be so, but am not aware of any "plumbed in" scale inhibitor which does not claim to be something else. If you mean a domestic water softener, which will, of course, reduce scale, these things are...

Both the species you suggest have prominent dark markings in the caudal peduncle. The OP's fish does not show such marking.

Parallel. If you place them in series, you will need to stop both in order to clean either which is not the case with a parallel setup. Additionally, since the water now has to go through two filters instead of one, the dissolved Oxygen available to bacteria is lower in the second canister then...

Serpæ can be downright aggressive little monsters. I certainly wouldn't suggest them for a quiet tank.

We have a couple of good hillstream keepers on the board, I'm sure they'll be along with specific advice. Generally they don't survive long in a typical tropical tank. They are hill stream fish meaning they generally want cooler water, a current and very high Oxygen levels. They graze algae from...

There are many unsafe contraception methods. In many parts of the world, continual administration of poisons, (to keep women in a health state where they are simply incapable of procreating), or abortifacients, "application" of damaging devices/procedures, and DIY/backstreet abortion are...

New plants + hard spirals = snails. It is most unlikely they are to blame for the deaths. It is entirely possible that the plants had been exposed to some parasitic or disease organisms which have taken your fish, however, that usually takes some time, they don't turn over within a day or so...

Schooling is a defensive strategy performed when fish feel threatened. It is rarely seen in typical tanks. If threatened fish school with their own kind, if REALLY threatened, they will school with similar species - but if the fish are that scared, you've bigger problems. Most barbs are totally...

Looks like a dyed white form of Gymnocorymbus ternetzi, (Black Widow, Black Skirt), a species commonly used for dying.

My first thoughts when I saw it was that it was one of the "blue" tetras, there are several species sold as such. Cochu's, (Boehlkea fredcochui), is a good bet. It does look like a South American fish whereas the Congo's are, of course, African. Thing is, after they arrive at the importers or...
