mandrian goby/dragonet infection?

[clownfishdaddy]

i recently have gotten this dragonet he was in with another male his size and they were showing clear aggression i have had him in this tank for almost 5 days now and he has these bubbles on his body they are clear almost they dont seem to bother him at all and he is acting extremely healthy since being in this tank constantly picking at pods even getting curious with the frozen food and his colors compared to when i got him seem to have become alot more vibrant alot BUT what could this be an infection some bacteria? it looks to be going away from when i got him but i still havent been able to figure out what it is and im kinda nervous for him
