Since this board has been up, we have found there are several questions that routinely get asked in order to help diagnose problems. If you can have that information to begin with in your post, we'll be able to help right away (if we can!) without having to wait for you to post the info we need.

1) Your water parameters - pH, Ammonia, Nitrite, Nitrates and salinity (if appropriate). This is by far the most important information you can provide! Do not answer this with "Fine" "Perfect" "ok", that tells us nothing. We need hard numbers.

2) Tank size and a list of ALL inhabitants. Include algae eaters, plecos, everything. We need to know what you have and how big the tank is.

3) Feeding, water change schedule and a list of all products you are using or have added to the tank (examples: Cycle, Amquel, salt, etc)

4) What changes you've made in the tank in the last week or so. Sometimes its the little things that make all the difference.

5) How long the aquarium has been set up, and how did you cycle it? If you don't know what cycling is read this: Fishless Cycling Article and familiarize yourself with all the information. Yes. All of it.

We want to help, and providing this information will go a LONG way to getting a diagnosis and hopeful cure that much faster.

While you wait for assistance:
One of the easiest and best ways to help your fish feel better is clean water! If you are already on a regular water change schedule (50% weekly is recommended) a good step to making your fish more comfortable while waiting for diagnosis/suggestions is to do a large water change immediately. Feel free to repeat daily or as often as you can, clean water is always a good thing! Use of Amquel or Prime as a dechlor may help with any ammonia or nitrite issues, and is highly recommended.

Note - if you do not normally do large water changes, doing a sudden, large water change could shock your fish by suddenly changing their established water chemistry. Clean water is still your first goal, so in this case, do several smaller (10%) water changes over the next day or two before starting any large ones.

Emergency - Massive MBU having issues after long transport

Post by Thefredpit »

I transported a 26" mbu 1100 miles the other day to its new owner via 40g tote. I transport monster fish across the country all the time and usually without any issues. Because the ph of the tanks I usually deal with are all around 6.8-7.2 I never really think about it, however the water at the location he came from is always extremely high(8-9), and has been a problem in the past, this time we believe it was probably 8.5. Unfortunately I forgot about it and the tank he went into was 7.2. I had done a 40% waterchange on the tote about 6 hours after picking him up with water around 7.0 ph. When arriving at the new owner he did have some tank water added slowly over 45 minutes before putting him into the 600g aquarium unfortunately he has been having a difficulty sinking. I figured he might of swallowed air so we treated him with a low dosage of epsom salt and prazipro. It has been 2 days and he is still having problems but doesn't appear to be getting worse. It was yesterday when I remembered about the ph problems at the other location. I know that this drastic of a drop will usually kill very quickly and the waterchange mid transport is probably what saved him. I also know that there isn't much of a treatment and a major issue with "ph shock" is how it compromises the immune system. Is there anything that can improve his odds?
