A Young Mature Serpae Tetra
This fish lives in Tom's 29-gallon aquarium with several of the other fish that you see here in the Listening Guides to Pet Fish Talk.
Brad in Troy, Michigan, sent this Picture.
Brad sent us this picture, taken with his cell-phone, while he was in a live fish store. One of the store's employees said these fish are killifish. Are they killifish? Tom and Nevin talk about this fish during this show.
Hey guys, We all refer to snails as moving slow, but this Cone Snail can shoot out a barbed dart at about 400 mph. Doesn’t sound like a “snail’s” pace to me! http://www.sciencedaily.com/ ... 24732.htm
Fish in the News from Dan in St. Louis
The audio for the recorded show has been slowly improving over the past 3-4 weeks though I do still pick up what I believe to be a ground-fault hum. The cure for this low (60Hz) tone is to carefully remove, clean and reinsert all analog interconnects including (especially) microphone plugs. The judicious use of a little DetoxIT, ProGold or Tweak may also be helpful.

hi tom and nevin, im a longtime listener to your show and while listening to one of your recent shows you discussed gouramis. i would like to share my experience on spawning honey gouramis in my 16 gallon tall aquarium. I consider myself a novice aquarist and lucky to get this fishto spawn.
honey gouramis (Colisa chuna) are small gouramis that grow 1.5-2 inches long. They are smaller compared to their cousins the dwarf gourami (Colisa lalia) and thick-lipped gourami (Colisa labiosa).Honey gouramis come from the Ganges flood plains in India and wild honey gouramis are actually drab brown/silver but fish breeders were able to create a honey yellow line. Once they reach maturity the males develop red coloration in the ventral tail anal area and black coloration in the ventral throat area. the females on the other hand remain pure yellow.
my aquarium had a penguin 150 for filtration but my aponogeton ulvaceous plant grew so large that it was able to create areas of slow flow creating a environment conducive for building a bubble nest (i am linking photos).
I do not know what environmental cues are needed for the spawning of this species but when the rains started to come in the San Jose ,CA area my male honey gourami built one nest and before i knew it spawned with the female in the tank. Their courtship ritual consisted of the male facing upward to the surface of the water probably trying to show off its colors to the female. Once i saw them displaying this behavior i decided to get away from the aquarium so as not to disturb them. Later on I saw the male picking up eggs from the bottom and spitting them to the surface of the bubble nest. It would also drive away any fish including the female honey gourami if it came near the nest.
However I had an apple snail in the aquarium and it ravaged the eggs overnight (the male couldnt drive away the slow moving but immovable behemoth). Not to be deterred by this setback the honey gouramis immediately spawned again. To reward their diligence i removed the apple snail and the guppies that were also in the tank so that the eggs will mature and also tried to do some research on how to care for the fry. I also had apistogrammas in this tank but i didnt remove them since they tended to stay at the bottom hiding among the broken clay pots i placed in the aquarium.
Knowing the possiblity that the parents and my apistogrammas will eat the free-swimming fry, I bought a 4 X 6 inch fry pen in order to house the fry. The fry pen is a mesh enclosure that you can place inside the same aquarium to ensure you have the same water parameters for the fry to develop.
In a day their eggs darkened in coloration. in two days you could see the tail and the yolk sac. they were developing fast before i could even grow infusoria. Instead I placed a ball of java moss and cut-up leaves an into the fry pen hoping that they contained protozoa which the fry can graze upon. i also discovered this product called liquifry which mainly consists of yeast and had one shipped to me ASAP. I also bought a pack of Hikari First Bites.
I used a syringe to suck the fry into the fry pen. The fry are so small that you can harmlessly use a syringe to get them. As I was doing this some of the fry would sink to the bottom of the tank but the male would diligently pick them up and spit them to the top of the nest. Naturally this made my task of getting the fry to the pen easier since the father helped me retrieve any fry that drifted away from the bubble nest. Below are some shots of the honey gourami fry in the pen:
Although i didnt have the optimal food to feed the fry, somehow a few survived with the diet i had available. Once I noticed the fry was large enough, I shifted their diet to newly hatched brine shrimp. I got a vial of San Francisco brine shrimp eggs and hatched them in a gallon container with an airstone to aerate it. I used a brine shrimp net to harvest the shrimp and dropped them into the fry pen. Soon enough they grew bigger and it was time for them to move out of the fry pen so I got an eclipse 3 gallon and transferred them there:
As you could see from the pictures with the baby brine shrimp diet they grew fast to look like miniature honey gouramis. I believe from the set of spawns i was able to grow ~40 honey gourami and i've sold them to three other aquarists and now I only have 9 left.
The rains are soon coming again and my remaining honey gourami are now mature and Im going to spawn them again this december.
thank you for being patient in reading my email and more power to the show.
best, Benjamin of San Jose

Callers during this Show ;^ }
Bonnie from Iowa calls and talks about her Goldfish that she's recently moved from her backyard ponds into a horse trough in her garage for the winter. This year she's heating the water in the horse trough. She also has a smaller horse trough that the water drains into from the bigger horse trough. In the smaller horse trough she's growing plants that help filter the water. Oh, the plants require plant lights, and Bonnie's got those too. Bonnie says she's got a little piece of San Diego in her garage during the winter. Just below are some pictures Bonnie sent after the show. Thank you Bonnie!! ;^ }
