my seabae hasn't really settled in since i got it. (been tumbling around) like 4 fours days ago it started to look deflated, brown at the tenteclas, and the mouth is gaping. just did a water change yesterday, and just added some fresh phosguard. it looks better since i did a the water change but still doesn't look right. i've had it for about a month and fed it twice but do for an other feeding. please help!
