We have been discussing the possibility of a Anne Broadmeyer 775-0030 [email protected] bus trip this year. Various destinations have been discussed, and the Board seems to think that Boston would be the best choice. It is still too early to give any details and we’re still open to suggestions if any of you have ideas.

My Experience with

This month we have a brand new author for the Wet Pet Gazette: Rich Grenfell! Rich’s first article is about his success in breeding the Bolivian Ram. Great article, thanks Rich! Everybody at one time or another who is as This month Ed Katuska again brings forth his seriously involved in the tropical fish hobby as I am, has had a quest or dream of spawning a should win a first place prize. I love it.

Squabbling among the females was the order of the day, so I decided to separate them. I set up a so-called breeding tank. I used a five Wet Pet Gazette, January – February 2001 gallon tank, some gravel, a few plants, and a the shell. I kept waiting but did not see the half coconut shell with a small hole in one female coming out of the shell, so I decided to side. For filtration, I used a sponge filter. Then investigate. I removed the shell from the water I put two females and one male in the tank. But and to my surprise, eggs -- tiny red eggs, about I soon found out that this was a big mistake 30 of them, so I put them right back and started because the females almost killed each other. I to count the days. But nothing -- no fry. I thought that I had learned from my previous without this type of problem, but I guess this mistake with A. agassizi -- but no!

But a few months went by and -- nothing. I guessed the fish were not sexually mature yet.
To make a long story short, out of about 30 eggs, 14 hatched and grew up to be 14 males - not one female! I had read in some books that chemistry. I had read that this particular fish the pH influences the sex of the fish. If the required very soft, acid water for breeding. For water is too acid, you get mostly males.

The only thing I was getting a pH reading of 5.5. The softness know is that I finally had spawned the fish I of the water I couldn't measure, but I guessed it always wanted to spawn. But the quest is not to be soft. The temperature was set at 80 over. It still remains. It will end when I finally see the beautiful female nijsseni swimming By this time, the male was about two and a quarter inches TL and the female one and a Footnote: Since I wrote this, I have fulfilled half TL.

At my first changes were done once per week, at 30% of meeting I met a few people that were breeders and I was instantly hooked. I just HAD to breed some fish! As you can see by the title of After about 6 weeks they had doubled in size this article, my first breeding experience and I knew I had a pair. There were 2 fish that would hover above the same rock, and chase all the other fish away. In talking to other NAS members, I was told that this meant that I first saw them at the store I happened to be working in at the time. And as was customary with fish that I was interested in, I put all 6 of fishroom and there they were…. About 60 or 70 little eggs on top of the rock that they had been defending. This batch ended up being bloodworms, and chopped frozen krill, and eaten, as did the 2nd batch. The 3rd batch meanwhile, I did some reading. The book that gave me the most information was American swimming stage, but disappeared 2 days after.

It is a 1992 advertisements normally associated with the T.F.H. publications. This was a refreshing experience. There are well over 300 color (mixture) of photos and hand drawings of the different species. There is an abundance of information on each genus's natural habitant, breeding habits and requirements.

Then again, there are some species that should be tried only when the hobbyist has had success with easier ones. Such species that may be considered difficult might include Pterolebias zonatus, Pterolebias hoignei and Cynolebias When discussing their breeding habits, killifish fall into three main categories: plant spawners, comfortable in aquariums of 2 1/2 to 3 1/2 soil spawners and peat divers.

Temperature plays a major role in keeping peat diving killis (as well as process. These fish are true annual species all other killis). If kept at lower temperatures with eggs capable of surviving extremely long (64' to 68'F), the Cynolebias and Pterolebias slowly but do not die as quickly as fish kept at higher temperatures. At lower temperatures they are also more active, in better colour and In their natural habitat, the peat divers live in small ponds and ditches in South America, which evaporate during the dry season.

The most commonly used medium is peat moss or peat fibre. Two methods are Some literature states that peat divers should commonly used: 1) the margarine dish method only be tried after the aquarist has successfully and 2) the bowl method. Both ways work very well and it is simply a matter of preference as necessarily true. There are some species of peat divers that are easily bred and equally beautiful too.
