Frozen foods

[crookedfish]

This maybe a silly question, but do you need to de-frost frozen food's like blood worm before adding them to the tank?

SOme do, some dont. I usually put mine in a small cup add a small bit of tank water and let them sit for a couple of minutes then into the tank. Sometimes when im in a hurry i just drop them in frozen and let the little finned piggies do the work. HTH

Either way, it'll work, don't worry. Even if you wont de-frost it, your fish will find their way to it...

Ok thanks for the info. I am just trying to work out why I have lost a couple of fish so it's probably coincidence that it was after I started feeding them frozen blood worm etc.

Water conditions all seem normal (Ammonia at 0, nitrite at 0, nitrate at 5ppm, ph at 7.9 lf's is at 8 - 8.4 so the fish are used to the ph level etc).

I have had one fish (zebra danio) die of swimbladder (tried to trat but was to late), another danio die without symptoms of any diseas, a bolloon molly die with no symptoms of diseas and I now have a giant danio swimminf a bit sieways (looks like swimbladder so will treat it). I thought these were all hardy fish so am a little dis-heartened. I am doing weekly 20% water changes etc so hopefully all will sort it's self out.

other than the mollie these are all hardy fish. Mollies are sometimes a little hard to keep and seem to stress easy, more so in newer tanks.
I wouldnt say it is a coincidence, though it might well be. Sometimes when fish receive food they are not accustomed to, and they like, they tend to pig out which can lead to problems. Some get constipated, some die suddenly(maybe they eat a piece that is too big ) and others just seem to stop eating for some reason. Be careful not to feed too much of a new food at one time. Perhaps use it as a treat to supplement at first. That way you will learn how much of this new food to feed your fish cause every tank is different so different quantities are required. HTH

i let them de-frost a bit, like tstenback mentioned, in some tank water

Thanks tstenback for that. Maybe it is because I am overfeeding!! I fed them with frozen daphnia last night (whole block) and it was all gone within minutes with the giant danio's looking very fat! and this morning one of the giant danios seem to be swimming off balance.

I didnt realise that fish would over eat. Looks like the de-frosting method is better as I can then meter how much I am putting in.

Thanks for the help

I believe that your fish is suffering from constipation. Feed them with some boiled peas (do not overfeed!!!).
What's the temperature in your tanks? Danios generally prefer temperatures between 65-72 F, so that could be another reason for your losses...

I had a betta die after swallowing a chunk of frozen daphnia whole. Since then i always thaw frozen foods before feeding.

 

[crookedfish]

The tank is sitting at around 25oC as suggested by the LFS, keeping it cooler than this will be difficult as we have been having some hot weather and the room temp has been reaching 26oC.

I might try some boiled peas and maybe some algae flakes.

Cheers

How big was the block?
