My Fish are Dying... Help!!!

[Gabriel_Martucci]

I need help, my fish are dying and I don't know why! So far this morning my Baby Paratilapia polleni and this evening my small pleco died. When the died they had almost like a clear/white coat of slime and looked pale. There eyes were clear and the pleco had a hole on its side (but the hole could be from anther fish). But I still have a clown knife and a bicher in the same tank and I dont want them to die too so I need your help ASAP!!!!

Thank you!

give the fish a general medication, ask your local specific fish store to suggest something. Likely chain stores wont be able to help much

Do a water change asap make sure you dose with dechlorinator.
List your water parameters like stated by Bonytang asap.

Another thing is the fins were mostly gone but the ones left broke with ease

Get yourself an API ammonia test. Take a sample to a lfs to test for Ammonia.
Please do the water change.

Its a possibility the Clown Knife may have killed the smaller fish.
