Who's the New Fish?

It's Pocky!

Recently one of my lionhead goldfish starting going through a dramatic change which happened in under 2 weeks (mostly within a week).

Before and After

My fastest growing lionhead 'Pocky' has rapidly lost his orange coloring. Overall Pocky's behavior has not changed and none of the other lionheads have yet to show any dramatic color changes. I can not pin-point the exact cause of Pocky's change although it could be due to... a lack of light (so I started leaving the light on at night where-as before I didn't really use it), low acidic pH (I have fairly high pH at 7.4+ which makes my water alkaline), food (I had started mixing in OmegaOne pellets last month which could be a possible cause), disease (so I treated the tank as a preventative), or age (I have had these lionhead for under 3 months now).

Before and After (mid transformation)

Whatever the case may be.. at least it is easier to distinguish Pocky from Sumo currently as it's almost like I have an entirely new fish. The little bit of orange that is currently left on Pocky is still rapidly disappearing so, we shall see what happens with Pocky over the next few weeks but I honestly feel this may only be age or gene related (which may perhaps mean that one of Pocky's parents was of the lemonhead variety, and if that's the case I believe Sumo is its sibling so I would perhaps anticipate Sumo changing colors as well). 

Dropsy

This week as I checked on my female guppy tank I noticed my main fish mom (the one that started all the current guppies I have) had developed a case of dropsy. I don't think I've had a fish get dropsy since about 5yrs back when I had some zebra danio's. I treated the tank with Maracyn Two and Mardel CopperSafe and within a few hours the female had unfortunately passed away. All my other fish seem to be doing fine, I moved the fry into the male guppy tank after 24/hrs of treatment and left the other adult females in the treated tank which I will clean out this coming week.

What's Dropsy?

Dropsy is a bit difficult to diagnose but it is generally a bacterial infection which could be introduced through poor water quality (high in nitrates). It could also be kidney/heart failure (possibly due to too many water chemicals), excess fluid to the liver, or other possible causes. It could possibly be contagious.

Dropsy Characteristics?

Rapid Breathing, Protruding Scales, and Bloated Body. In early and latter stages of dropsy you may notice the fish going to the surface often for air, possible lack of appetite, or even spends most of its time at the top or bottom of the aquarium. There may also be a change in color (female guppies tend to turn a bit gray on the body).

Dropsy Treatment?
As dropsy is hard to diagnose it makes it difficult to treat. Moving the fish to a quarantine tank may make matters worse due to the stress it will cause on the ill fish. If the fish is already showing the bloated spiny appearance than chances of survival are probably slim. An aquarium salt bath may help to draw out the fluid in the fish. Some medications that may help are penicillin, tetracycline, and nalidixic acid. Water changes and clean water are a must to help prevent fish from getting dropsy.
