3/5 clamped fins?

[AlexXx]

In my sorority i have 3/5 girls with clamped up tail fins. I know that could mean they are stressed... but nothing has changed in their environment. Could it mean they are sick? I just had a death in the tank, cant figure out why though. They seem to all be swimming around fine, but the 3 are just clamped up! its so sad looking, especially my yellow dbt female.... shes got such a pretty fin :(

Any idea?

could be stress, could be ammonia build up, or toxins due to a death in the tank?

id change some water in case

[doggyhog]

Change the water. Add a little more salt then usual. I hope your pretty girlies are OK!!!!!

I checked the ammonia right after the death (she didnt acctually die in the tank, i took her out a day and a half she actually expired). It was Zero! Then i did a 30% watch change.... Im beginning to think they are getting cold! The thermometer is at 70ish, i gotta get them a heater today, its acctually gotten into the 60s here in so flo.

Alright im going to get a heater in a bit, gotta change a few tanks waters.... whats the best heater for a 10 gal! what wattage? ive never got one yet, so where are they cheapest usually?

Walmart has them for around $13 (depends on sale) which is great bc the one I bought for my 10 gallon was $20 at Petsmart.

Here is the link. It has great reviews.

WOW! Its always $13 here, and goes on sale for $10 every few months.
