They'll Never Be The Same

I have a 30 gallon heavily planted freshwater tank, currently home to a mated pair of Opaline Gourami and a school of Danios.

I was out of the country for 6 months, during which time my father was taking care of my tank. He had to move the tank to have some flooring redone and didn't follow my instructions. He added all new water back to the tank when he drained about 75% of it, and it killed off my Danios and an L187b that I had--probably because of trace amounts of chlorine. Needless to say, I was livid. :mad2:

Since I came home a few months ago, I've gotten the tank back on track. No ammonia or nitrites. Healthy nitrate levels, etc. The tank has been established for years and never had any problems before this incident. Although they survived the move, my Gouramis did not take it too well. When the other fish started dying, they became noticeably upset and began hiding. Before this, they had been very dominant fish in the tank, always out and guarding their food. They don't come out at all anymore. When I got back, I rearranged the tank hoping it might encourage them to come out (and to re-root all the plants my father tore up looking for the Danios), but they hide at the bottom of the tank in the plants ALL THE TIME. I also replenished the Danio school, hoping it would make them feel more secure to have more live fish in the tank.

They come out occasionally at night but if anything in the room so much as moves, they will crash into anything in the way to get back to hiding. They've been like this for about three months. I miss their old, happier personalities. And they're supposed to be a top fish, but instead they're constantly as buried in the vegetation as they can get. Are they just suffering from trauma? Is this the result of damage they may have incurred? Is there anything I can do to make them more comfortable? I've tried adding stress coat to the water. It doesn't seem to have any effect. :confused:
 
I too have experienced this behavior with gouramis. Try spending more time in front of the tank and add a little food each time. They possibly may need to relearn to associate you with food rather than a dangerous predator. ;)
What is the avg temperature of the tank, btw? Just curious.
 
I agree with some retraining. What's their favorite treat? Frozen bloodworms or brine shrimp? Try giving them small amounts at random times throughout the day. Maybe 3 or 4 times one day, once another day, etc. Hopefully you will teach them that each time they see you around there is the possibility that favored treats may show up too.

To offer another possible explanation, it could be a latent illness/infection. My honey gouramis (only gouramis I have) were very happy - out and about all the time, mating colors constantly. After a temporary water quality issue from which a tankmate developed pop-eye, they were hiding all the time, and hanging out on the bottom often. I kept changing the water, thinking that with enough fresh water they would return to their happy selves. Suddenly one day, the male didn't have enough energy to swim or stay upright, and had mild pine-coning. I immediately removed him to medicate, but it was too late. I currently have the female in a hospital tank, and she just finished a first course of medication, but has really ballooned up. I am convinced if I would have medicated them earlier they would have had a better chance of kicking what is likely a bacterial infection that was bothering them at low levels for weeks.
