Videos of Ted’s fish in his fish room.

Laimosemion (Rivulus) rectocaudatus

The fish that we collected on the trip to Peru arrived yesterday.  We got a couple dozen killifish, Laimosemion (Ruvulus) rectocaudatus, that we found in the ditch along side the road.  The little run is water was lousy with these killies.  We could have collected hundreds of them.  The fish is pretty and mean, and also good jumpers.  I put them into a 20-gallon tank with only a few inches of water to acclimate them.  They were spread out a day after this video was shot, but I noticed that they were doing their best to jump out of the tank, and grabbed the video camera…  Enjoy.

U.S. Virgin Islands

This has been a Summer for checking items off of my bucket list.  We took a family vacation in June to the U.S. Virgin Islands, and I finally had the chance to see Caribbean reefs in person.  I shot a lot of video, and will post several from the trip.  These first two are from St. Thomas.  The first is from a boat trip we took out to a sanctuary, and the second is from the cave at the hotel.  The third is a snorkling tour in Trunk Bay, one of the highlights in the Virgin Islands National Park on and around St. Johns.  The shorelines of the US Virgin Islands are covered in reef animals.  You can hardly go wrong putting on a mask and jumping in the water…

Crenicara punctulatum… The Hermaphrodite Cichlid

Once upon a time, all of the checkerboard cichlids were in the genus Crenicara.  When the genus was split, two fish were left in the genus and all the others went into Dicrossus.  The type species is C. punctulatum (the other is C. latruncularium).  This original checkerboard cichlid is a fun fish to keep.  They are not overly demanding, though they do not do well in dirty water.  This fish is a sequential hermaphrodite.  All of them start off looking phenotypically female.  As a group of young fish mature, the most dominant fish will grow faster and become the breeding male.  He will pair with a female that will also grow, though not as larger, and take on brighter colors and redder fins.  The rest will stay comparatively small… as though they are suspended in growth.  If the male is removed, a new male will arise (usually the previous dominant female).  The sex change is not reversible.  So that means that the easiest way to get a breeding pair is to pick up a group of 6-8 juveniles and let them grow up.  Once a pair forms, move the rest to another tank and another pair will arise. Fun fish!

Bolt (Volt) Catfish – Aguarunichthys torosus

Here is a ‘monster’ fish that is not so much a monster.  The bolt catfish is predatory cat that grows up to be about 13″, so not outrageously large.  They are active catfish with voracious appetites, and are really really good and chasing down and killing small fish.  The fish in this video have only been here a few days, and they are settling in nicely.  When they got here they were in pretty bad shape, as evidences by the few that are really thin and some bent and eroded barbels, but they are coming around.  I am feeding them guppies, Repashy Meat Pie gel food, black worms and chopped earthworm.

Tatia sp. Wood Catfish

I have been getting more and more interested in wood catfish over the past few months, and one of the species that I have brought in is a large Tatia sp. from Peru.  And I do mean large…  The first four I got back in late February were all about 10″ long, and I really liked them.  But they were sold pretty quickly.  So I got some more.  10 more to be exact.  They are almost through quarantine, and six of them will soon move into a 180-gallon aquarium that is being prepared for them.  I am really hoping to get them to spawn!  Here is a video of them in their quarantine tank, feeding on chopped earthworms.

Today in the Fish Room

Here is a short video of a few of the dwarf cichlids that are set up in spawning tanks.  The Apistogramma cacatuoides ‘Pucallpa’ have 10-day old fry.  A first look at the wild Pelvicachromis subocellatus ‘Moanda’ pair I got from Oliver a couple weeks ago.  An update on the Nanochromis splendens that are starting to mature.  And a look the the A. bitaeniata ‘Rio Tigre’ that are, hopefully, close to spawning.

Apistogreamma alpahuayo

Here is a video of one of the black chin apisto types I am working with right now.  This is the ‘common’ variety, which means that it is a mix of fish from various places and given the descriptive term ‘yellow form’.  You will see two distinct types of males in the video.  I also have some of the same species from specific river systems (Rio Tigre and Rio Aguaytio).  They are different, though some of the fish in the ‘common’ look a lot like the Aguaytio form.  The black chin is very similar to A. cacatuoides.  They are often mistaken for each other.  One of the easiest featured to look for is the gap between the rear end of the lateral line stripe and the caudal peduncle spot… that gap is characteristic of A. aplpahuayo.  I really like this whole group of cichlids, and it seems like every river in Peru has a different form.  Enjoy…

Apistogramma panduro… Mirror Therapy

Here is a video of a pair of wild A. panduro that are in the process of getting ready to spawn.  This species is one of the nijsseni-group apistos, and as such it can be pretty aggressive.  They prefer to spawn in pairs, and other fish in the tank can take a pretty good beating from a dominant pair.  This can be a problem when a pair is not fully bonded.  If the male is not receptive to the advances of the female, or if an amorous male does not get the response he wants from a female, then there is a chance that the male can attack and kill the female.  Mirror therapy can help…  by using a mirror to solicit a territorial response by the pair, their bond is made stronger.  You will see in the video that the male is very aggressive on the mirror… he hits it hard multiple times.  The female will also join in on the defense, which is a good sign that the pair is bonding well.

Beckford’s Pencil Fish…

I keep a lot of Beckford’s pencil fish (Nannostomus beckfordi) in with my dwarf cichlids, and in my photo tanks, as dither fish.  I did a big water change on the photo tanks today, and two males in one of them started to spar with each other… so I grabbed the camera.  Enjoy…

Apistogramma trifasciata

Here is a video of a new group of A. trifasciata.  When I set up apistos for breeding, I start with multiple males and females.  Once a dominant male becomes established I remove the extra males, otherwise the dominant male spends ore time worrying about the competition than he does spawning…. as you will see in this video.  I removed the extra male after shooting this footage.

This species comes in from the Czech Republic as A. trifasciata ‘Macilliensis’… but that is not really a valid name.  This is a basically a nice tank strain trifasciata.
