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.

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...

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.
