I purchased Tex at 1-1/2" about 2-1/2 years ago. He has killed or seriously maimed all tankmates. I originally purchased him in a lot of three. Then after he killing his original companions, I introduced another pair about his size, same result. He's taken out two plecos and a pictus. He's ravaged two native sunfishes that were twice his size at the time. He is now almost 7" long and a loner, a wonderful pet who is genuinely excited to see me when I arise or return from work (perhaps it is because meal worms fall from the sky when I am around). He's to the point where when I add 20-25 small minnows, he finishes them off overnight.

I have had an electric blue dempsey for a little over a year. The store where I bought him knew I was keeping a community tank, and have had no problems with him until now. I have 2 species of barbs, chinese algea eaters, 2 pearl gouramis, and had an angel fish until about 3 weeks ago. The dempsey never bothered anyone until I added 2 clown loaches two weeks ago. The dempsey killed one on the loaches last night. Is he just getting aggressive now, or could this be specific to the loaches?

My dwarf neon rainbows are a delight to keep! They are active, happy, and hearty eaters. I started with a trio of 1 male and 2 females. I quickly added 2 more males, and 5 more females for a total of 10. They are a beautiful grouping in a 20 gallon. I would highly recommend a tank dedicated to them.

Ps. I did receive these from a LFS who had just gotten them in and within a week all of them did develop ICK, but treated with Aquarisol they did quite well.

I have had my dwarf neons for about six months. The are great fish. Their colors get brighter with age. They are a lot of fun to watch. I have 3 males with 1 female in a 20 gallon tank. I know this is not a normal male/female stocking ratio, but my female seems to be doing quite well. The males will make advances at her for a few minutes in the mornings when I turn the aquarium light on. She doesn't pay much attention to them anyway. Beautiful fish and enjoyable to keep.

Hi!
When I first got my dwarf rainbowfish, I asked for 2 females and 1 male. But when I got home I found out I had 2 males and 1 female. They all looked healthy and were feeding well. A week later I found one dead. I could not work out what was wrong so I watched the tank carefully. A week later I found another one dead. I was only left with a female. I was sad because they are amazing fish and I was now worried about my female. Now- 3 months later she is still around and doing great. After the last one died I added bacteria medicine. This worked and I saw a great advance in the females behaviour. She is shoaling with my other fish- but I feel it is unfair to leave her by herself. and wonder if I should I get more dwarf rainbowfish. I recommend these fish- they are great to watch. Just make sure they are healthy when you get them.
Thanks!

These are beautiful fish. I have four different species of rainbows in a 37 gallon mixed with a few emerald and peppered corys and they do quite well they are fun to watch. Just be careful what fish you mix in. In my experience they are also killers yes killers .... Happy fishing

When I was first establishing my 20g tank I was persuaded to add this adult male dwarf neon rainbowfish... I quickly read up that these fish are happier in groups of at least 5 and to keep them the same sex with that many. So I added three more males that appear to be juveniles, though I can at least see their colors. (the shop only had the three, they gave me a fourth that was female on accident) and Bo (the adult male) is absolutely brutal with them. Chasing nonstop. Food aggressive... just today I found one of the other males dead. His scales on either side looked nipped to pieces. To be honest I don't know if that happened before or after he died but he wasn't sick or anything prior. Is it possible that the adult is actually better off by himself? I would like to avoid any more casualties. I should note he's only aggressive with his own kind. The other fish he leaves alone.

I have misjudged this wonderful fish. As i noticed the shoal of Rasboras were frightened by my shoal of Black Neon Tetras, I misunderstood the fear for agression by the Black Neon Tetras. I was gazing at them and realised that the Rasboras must have been unaccustomed by my Black Neon Tetras (as they are new to the Coummunity) thus frightened, days ago. If one spends time noticing the activities of a Community tank, one can discover that there is beauty in these tetras.

I picked out two Texas green cichlids at the store And it just so happened one was ale and one was female. We had them a month and they laid eggs and had babies. I have been so impressed with the male and female partnership when it comes to caring for the babies. We are about four weeks out since they hatched and we just got a fry holder to put them in because we noticed they are slowly disappearing. There are about twelve left. Not sure what's next mom and dad look frisky again. Lol
