I bought the fish trap I caught the triggers and the butterfly fish.The fish trap works but what I did was silicone a piece of acrylic onto it so the trap is at the top of the tank.I was feeding food into the trap and this way I didn't have to stick my hands in the tank.The fish started to go in the trap but theniger wouldn't go in till the second day he was hesitant but he went in once, I let it be not to rush then there were 3 fish in there I closed the glass that was it.I feed mysis, brine shrimp,dryed brine shrimp,flakes and pellets(both types),some of the pellets do fall to the bottom plus I see bugs on the glass so there is something for the fish to eat.On another note my Lemon peel died.I was upset for some reason the fish that die go into hiding and stop eating.The angel was hiding the last 2 days.I did see him come out once or twice but for some reason he stopped eating.I don't know why the fish do this.Its not like any other fish was bothering him.I also did add some selcon to the fish food.I did this twice a week.Maybe I won't try that again.I did see the spotted goby start to eat.I have another 2 types but good luck trying to find them.I did find some type of emerald crab in the tank last night but I didn't catch him.I saw him when the lights were off.I will try the crab trap I have to pick one up.He wasn't big probably smaller than a quarter but I don't want any problems.I have had emerald crabs before and they never killed anything.I will try to get the trap to make sure thats what type of crab he is.I installed my fish feeder to dispense pellets 4 times a day.I have read anthias like to eat several times a day.I do hope they will eat pellets.I put several types in the feeder.I will still try to feed frozen foods but I hope they eat the pellets.I don't want to lose another fish.I think I will stop buying for now.I go overboard when I go to a pet store.
