Decisions

I just lost my favourite guppy in the space of an hour and a half after the tank had other problems (i posted these on the emergency section)...the tank is 18x12x12" and i'm left with out about 15 guppy fry in a breeding net and 2 amano shrimp....there were no obvious symptoms on the guppy, and it had been the healthiest fish until then...

What i'm after is some advice on what to do with the fry/tank...would it have anything left in it that would harm the fish?
the results cam through as:
Ammonia: 0.75
Nitrite: 0
Nitrate: 3
This was after the death of the male guppy.

I'm not left a bit puzzled as to why it died and what to do with the tank and fry now.

First off, you have ammonia present which is bad and should not be present in a cycled tank. I would imagine it would be particularly toxic to fry. You need to start doing water changes (10 to 5 percent) as often as 2 or 3 times a day if needed to get and keep the ammonia down below .25 ppm. Did you recently add more fish to cause the ammonia or is it a new tank? How many and what type fish do you have in it (just the fry and shrimp?)?

i've already started doing water changes, i've changed about 10% twice today....i haven't recently added more fish, but obviously the fry are 3 days old so would that have increased the ammonia? i have just the fry and shrimp, my main tank is seperate

Did you just set up the fry tank or has it been running? You might want to consider adding some filter media from the main tank to the filter on the fry tank. That would help it cycle faster and solve the ammonia problem.

I don't know what may have been the problem with the guppy you lost. Could have been age but since you also lost 2 others in the tank it was likely a disease or parasite of some type. Was there any sign of disease or marks that shouldn't have been there? i don't know much about diseases at all as I have been very lucky to have my tanks stay disease free.

its been running for about 2 months now and that was using an established fitler media....there was no sign at all, externally or in the behaviour until that hour and a half....its left me puzzled a bit but hopefully the fry will be ok with regular water changes
