Ive had 2 figure eight puffers for 2 months now. We did a full clean up and water change a week ago due to an algae build up. we didnt change their filters to save the good bacteria in it. their water has stayed pretty clear ever since but they have been acting strange. They sit at the bottom nearly all day, their back fins are always closed up and they have little white specs all over them and their fins. One has now developed a white film over one of his eyes. They both have been scratching or hitting themselves on the rocks in their tank and one was swimming up the current of the filter for about an hour straight until i moved the filter. they have a good diet of ghost shrimp, snails, crill and bloodworms. Theyre in brackish water and have been since we got them.
pH: 7.4
ammonia: between 0-0.25
nitrate & nitrite: 0

They have Ich. Slowly raise their temp to 82 degrees. You can also add some aquarium salt. Just follow the instructions on the back of the container and be sure to dissolve the salt before putting it into the tank.
The puffers' eye has clouded over because he probably injured it while scratching. It will most likely heal once the Ich is gone.
I also agree on the cycling. Do a 50% water change to get rid of the ammonia.

Do a 90% water change and gravel clean the substrate every day for 4 or 5 days.
Make sure any new water is free of chlorine/ chloramine before it's added to the tank.

Clean the filter if it hasn't been done in the last 2 weeks. Wash filter media/ materials in a bucket of tank water and re-use the media. Tip the bucket of dirty water on the garden/ lawn.

Increase aeration/ surface turbulence to maximise the oxygen levels in the water.

Raise the water temperature to 30C (86F) and keep it there for 2 weeks. Then reduce it to 24-26C.

The following link has information about white spot and various ways to treat it. Heat is the safest method. The first post on page 1 and second post on page 2 are worth a read.
