Hi there,
I have a 30"x12"x14" tank - 18 gallons? I have an angel, a silver dollar, two clown loaches and a pleco.
The angel (4"), the oldest, is bullying the silver dollar (4") to the extent that it now hides in the corner of the tank all the time. As you can probably tell, I'm a bit of an amateur, but I was wondering if removing the angel from the tank might help. I only have one tank however so am not sure how to do this, I have heard that aquarium might take fish back on exchange, but I'm worried it might be a bit old for that - how long do angel fish live for? Mine is nearly three years old.
The pleco and clown loaches spend 95% of their time hiding too. I thought this was fairly normal until I saw a friend's clown loaches, who are quite active in their tank. The pleco comes out at night as normal, but is not as active as when it was smaller. It is now about 8" nose to tail.
Really what I'm after is just some general advice about fish keeping. I'm worried about the happiness of the larger fish and if exchanging for smaller fish would be better for all, then I will do that. If there are steps I can take to make the present ones happier then I will galdly follow those.
Many thanks in advance
