Daniel had to drive to work yesterday because he was so late he could not take public transportation.  After spending the morning posting many of your wonderful letters, he noticed Boris and Medea Luna obviously distressed at the top of the aquarium.  The two remaining Cardinal Tetras they share the 40 gallon aquarium with were gasping at the top as well.  The last remaining two year old Blue Ram was dead.  This followed two partial water changes in two days.  Upon returning to the home office after Spring Break, Medea Luna’s pectoral fins did not look good.  The suspected love nips from Boris appeared to be a fin rot fungus and internet research suggested frequent water changes, so first 15 gallons, and the next morning 10 gallons of water were changed and Stress Coat+ was used.  Next morning, just as Daniel was about to leave, the distressed fish looked bad.  Daniel couldn’t skip work, so he quickly scooped up the four survivors and transferred them to the Grow Out aquarium.  There wasn’t time to make sure the transfer would be successful, so Daniel drove off to his morning lecture.  Thursday is a very long day, culminating after an evening lecture ending at 10:15 PM.  Throughout the day, Daniel couldn’t help but to worry about the state of affairs with the mated pair of Angelfish that have been under Daniel’s care for two years.  Upon returning home at nearly 11 PM, Daniel was relieved to find the four distressed fish well and hungry, though there are also 11 Rummy Nose Tetras and about 50 Angelings only a few months old also in that aquarium, not to mention a Cory Cat that always hides under a rock.  The largest Angelings will have to go to Tropical Imports this weekend and Boris and Medea Luna’s home will need some major attention.  Looks like a busy weekend.  Sorry no new photos, but here are the couple before the averted tragedy.

Lefty and Digitalis just finished a meal of mosquito larvae that are growing in the bird bath.  They enjoy eating Mosquito Larvae more than just about anything.  I am not certain exactly how old these Fry are, but it is somewhere around four weeks.  They don’t all grow at the same rate.  Last weekend, after taking all the Angelings to Tropical Imports, I transfered 52 of Boris and Medea Luna’s fry to the growout aquarium, but I can only account for twenty, and they are all larger.  I fear the smaller fry were eaten by the RummyNose Tetras, really just a school of tiny Piranhas.

Boris and Medea Luna chose a fortuitous time to spawn.  Yesterday I took 24 small angelfish to Tropical Imports and traded them for food and two Rummy Nose Tetras.  I then moved 52 Angel Fry from Boris and Medea Luna’s last successful spawning, the first in 2 and a half years, into the grow out aquarium.  I kept the smallest of the previous brood, that of Lefty and Digitalis, to raise with the newcomers.  Lefty and Digitalis laid eggs a few days ago and I cannot find them.  I’m not certain if they are gone or if they are hidden.

Boris (top) and Media Luna two years later

Boris, Medea Luna, Lefty and Digitalis are about to celebrate their second anniversary since moving to Mt. Washington shortly after the nitrates dropped in the aquarium we had set up two weeks earlier.  Boris and Medea Luna with Digitalis laid a batch of eggs four days later on March 31, 2009.

Boris and Blue Ram

Boris and Medea Luna laid a batch of eggs about a month ago.  The young were removed with a turkey baster just before they became free swimming.  They are living in the bathroom in the nursery aquarium.  The parents moved them about and chased away the single Blue Ram and the two Cardinal Tetras, the last remaining fish from the originally stocked aquarium from March 2009.  Lefty and Digitalis have a brood of 2 week old fry right now.  This is the largest brood ever I believe.

Boris and Medea Luna are paler than usual tonight.  I will photograph Lefty and Digitalis tomorrow when there is daylight.

Rummy Nose Tetras and Angelings

These little beauties are the offspring of Lefty and Digitalis and they were born quite a few months ago.  I cleaned out the filter in the growout aquarium.

Breeding Stock Fledgling

This guy is from two broods ago.  I saved the prettiest of the brood.  This fledgling is the pick of the litter.

Boris and Medea Luna have hatched a small clutch of eggs in the past week.  Several days ago I counted 21 wrigglers.  The community aquarium in which they reside has a drastically reduced population since last year.  The tanks was most likely overstocked and the ecosystem could not handle the numbers.  Now, other than the pair of Angelfish, there is a single Blue Ram and a pair of Cardinal Tetras (down from 6 and 10 respectively).  I fear for the lives of the wrigglers the minute they start to swim, though nothing has been quite as bad as the bands of marauding fledgelings that for only short periods of time resided in the community aquarium.  The hatchlings may get sucked into the filter, or eaten.

This afternoon, Boris and Medea Luna began to lock jaws.  The bottom line is that though aquarists have long witnessed the jaw locking of Cichlids including Angelfish, and though it is commonly associated with mated or courting pairs, it is uncertain if this is aggressive behavior, romantic behavior or dominance behavior.

As an aside, Lefty and Digitalis have a small brood that hatched the day before the fry of Boris and Medea Luna.

Aquarium Rainbow

September 3, 2010
Every afternoon when the late afternoon light comes in through the west door, there is a beautiful rainbow on the wall behind the growout aquarium.  The Rummy Nose Tetras and young Angelfish get very active at that time.
