Secondary Structure. This is where the secondary structure comes in. The secondary structure is a repetitive 3-D structure of a protein. These are things that people often come into contact with when they're looking at protein structures.
If your fish are more heat tolerant, try increasing the temperature to 32 C/89.5 F for the first 3-4 days to kill the Ich. Then reduce temperature slowly to 30 C/86 F, and hold it there for an additional 6-7 days, or until a total of 10 days have passed.
Ich has three life stages, which are important to understand for proper diagnosis and treatment. When the parasite is visible to the naked eye, it is a nearly fully developed trophont which has burrowed under the fishâs mucus coating where it is protected from chemicals (medication).
