Identify please

[Oldspartan]

Long story short ...

A few days ago I took the two grands with me to pick up the corner tanks at the not so LFS. While there as I talked with people the grands peppered me with wants. Mainly we want to pick out fish to take back. A tank was cycled and ready for denizons so I said OK you can each pick two. They did. I was still busy so I gave them my CC and told them to go ahead and pay. They did.

Upon reaching home I realized they did not get a receipt. Not a biggy, EXCEPT, I have no idea what these creatures are

First pair:

Second like this:

One of the above has a yellow streak going down its back, the second does not.

I am not trying to be lazy with my research and have done some browsing without success. Two grands and a wounded wife seem to be taking up my time and I am not going to be able to realy dive into a book until the two little urchins return home tomorrow.

There is also a BN Pleco, full grown, and a bllod parrot in the tank, (This is Linda's dream fish and was a Valentine gift).

1st one looks like a Sahyadria denisonii ( Rose line shark, Denison barb ) the 2nd looks like rainbow fish... too much reflection for me to identify further

 

[BigDog]

The first fish appears to look like a Sahyadria denisonii

The 2 fish is a rainbow fish

 

[WhistlingBadger]

I believe you have a Dennison barb and a Lake Kutubu rainbowfish (Melanotaenia lacustris).

A picture from the side without that reflection would help more to determine the correct rainbow fish species.
And yes, as already stated, the first one is a Denison barb.

 

[CaptainBarnicles]

I agree with the above...they both ought to be in groups though

 

[Oldspartan]

Thank you all. I have confirmed in my picture book.

Yes, thank you. I will correct that with 4 or 5 more of each on Sunday.

 

[Oldspartan]

OK --- I have read on these two species.

The Roseline sharks apparently get to be 6 inches and need a group of six, Fifty-Five Gallons for the first and 5 gallon each additional. That amounts to a 75 or 90. Another tank that size is simply not going to happen in the fish room, and I already have two tanks in the bedroom and two in the living room. I do have a 55 available and can shoehorn it into the fish room, but prefer not too because I want to use it during the summer in the pond house. I love these fish but will apparently need to call the not so LFS about a return.

The Lake Kutubu rainbowfish is apparently a Turquoise Rainbow Fish. Again, it appears I need to keep six and the tank needs to be 55 gallons. Same quandary as above.

Am I correct in my assessment?

If so I have learned a great if uncomfortable lesson.

not going to argue with your research, I'll only say I get away with less tank than that, with 5 denison's in a 55, along with all my Hillsteams

I think you can stock to higher levels than I can because of your plants (?). Perhaps I am wrong.

We are transitioning to live plants but have a long way to go I think before we actually get any significant help from the. At current time I prefer understock because I think it forgives my many mistakes to some degree. More experience will bring higher stock levels. Not crawling anymore but still toddling. At least I like to believe.

I do over filter as well...

 

[WhistlingBadger]

It isn’t really an issue of filtration; it’s an issue of space and activity levels. Both of these species are very active. I’ve kept both in a 55 gallon and they did “ok”. The kutubus even spawned a few times. But after keeping rainbows in a 150 gallon and seeing how much more active and interesting they were, I don’t think I would keep them in a 55 again. Same with dennies. They have that torpedo shape for a reason! Maybe a 55 with a strong current would make them happy.

Kutubu rainbows have some of the coolest social behaviors I’ve ever seen in my fish. They really communicate with color flashing. I never really figured out the language but It’s really fun to watch them.

 

[CaptainBarnicles]

I swear my rainbows get the 'zoomies' like a dog would ordinarily I'd be inclined to think they were flashing with an irritation or contamination in the water if I saw it from any other fish, but when rainbows get excited they really do make use of all the space available to them and they're so fun to watch

 

[GaryE]

Kutubus would do okay in a 4 foot tank, ideally one with front to back room. Height would be optional. They aren't high speed swimmers and they don't get huge. I find them very beautiful, but they very often seem to have tb lesions, even in stores. Their price has dropped radically, but so has their lifespan. It really is a shame, because they are under pressure in the wild, but often diseased from the farms.

I've never kept Denison barbs, because the first time I saw them, they were a new fish that had arrived close to adult size. I looked at that and figured with a torpedo shape, silvery scales and their overall demeanour, this fish was going to want to swim fast and far. They are incredibly beautiful fish, and are tempting, but I couldn't keep them right. As well, and I don't know if this has changed, they are like tiny threadfin rainbows, or clown killies in the trade - most wholesalers only receive males from the farms. So if you keep shoals, you don't get to see normal shoaling behaviour. From a fish watcher's point of view, they can be a bust. It isn't good for fish breeders, either...

 

[Magnum Man]

my Denisions are comfortable enough, that I get to watch nuptial dancing regularly in my highly flowing Hillstream 55 gallon tank, and while active, aren't swimming from end to end like they are confined in too small a space...
